Klebsiella pneumoniae and poultry as reservoirs

Frontiers in Microbiology | September 2021 25 September, 2021 Klebsiella pneumoniae is a well-studied human pathogen for which antimicrobial resistant and hypervirulent clones have emerged globally. K. pneumoniae is also present in a variety of environmental niches, but currently there is a lack of knowledge on the occurrence and characteristics of K. pneumoniae from non-human sources. Certain environmental niches, e.g., animals, may be associated with high K. pneumoniae abundance, and these can constitute a reservoir for further transmission of strains and genetic elements. Can poultry serve as a zoonotic reservoir? Read More

Decreased incidence of infections caused by foodborne pathogens during the COVID-19 pandemic

MMWR Weekly / September 24, 2021 / 70(38);1332–1336 24 September, 2021 The 26% decrease in incidence of infections caused by pathogens transmitted commonly through food during 2020 was the largest single-year variation in incidence during 25 years of FoodNet surveillance; widespread public health interventions implemented to prevent SARS-CoV-2 transmission might have contributed to this decrease.
During 2020, FoodNet identified 18,462 cases of infection, 4,788 hospitalizations, and 118 deaths. The overall incidence was highest for Campylobacter (14.4 per 100,000 population), followed by Salmonella (13.3). Read More

Salmonella in livestock production in Great Britain - 2020

23 September, 2021 This annual publication provides data on reports of salmonella in livestock species in Great Britain (England, Wales and Scotland) which was collected and collated by the Department for Environment, Food and Rural Affairs (Defra). Each year includes data from previous years for comparative purposes.
During 2020 there was a reduction in non-statutory surveillance and clinical diagnosis submissions in many species which was consequence of the Covid-19 pandemic and associated lockdown measures. This should therefore be borne in mind when comparing2020 data with previous years.
Salmonella in humans: In 2020, a total of 5,263 isolations of Salmonella from humans were reported; this is 45% lower than in 2019 (9,588 isolations) and 48% lower than in 2018 (10,143 isolations). Read More

Germany: H5N8 in dead seals

20 September, 2021 Avian influenza virus has been detected in three dead seals found in the Schleswig-Holstein Wadden Sea. First, several dead seals were examined at the Institute for Terrestrial and Aquatic Wildlife Research of the University of Veterinary Medicine Hannover in Büsum, announced the Ministry of the Environment on Monday. The virus subtype H5N8 was detected in two animals. The Friedrich Loeffler Institute as the national reference laboratory has now confirmed the infection in three samples. According to initial investigations, there is a great similarity to the avian influenza viruses detected in wild birds in recent months. Read More

It reviewed the results from source and contact research, estimates of the introduction time, and virus similarities for the infected farms. Read More

Broad coalition calls for modernization of poultry food safety

7 September, 2021 A broad coalition of four major poultry producers, Consumer advocates, food poisoning survivors, and scientists jointly asked the Agriculture Secretary Tom Vilsack to meet with them to hash out a modernized, science-based approach to reducing salmonella and campylobacter illnesses in poultry production.
The letter sent to Vilsack reads, “While progress on reducing foodborne illness has been at a standstill, scientific knowledge of Salmonella has greatly increased and recognized best practices for Campylobacter and other pathogens has advanced. Science tells us that current performance standards do not effectively target the particular types of Salmonella and the levels of bacteria that pose the greatest risks of illness, and the overall regulatory framework does not adequately harness modern tools for preventing and verifying control of the bacteria that are making people sick.” Read More

An outbreak of HPAI H7N7 in Australia - 2020

Microorganisms 2021, 9, 1639 27 August, 2021 In 2020, several geographically isolated farms in Victoria, Australia, experienced an
outbreak of highly pathogenic avian influenza (HPAI) virus H7N7 and low pathogenic avian influenza (LPAI) viruses H5N2 and H7N6.
The Victorian outbreak also detected LPAI H7N6 in emus at a commercial farm. Novel influenza
A viruses can emerge by mixing different viral strains in a host susceptible to avian and human
influenza strains. Studies show that emus are susceptible to infections from a wide range of influenza viral subtypes, including H5N1 and the pandemic H1N1. The emu’s internal organs and tissues express abundant cell surface sialic acid receptors that favour the attachment of avian and human influenza viruses, increasing the potential for internal genetic reassortment and the emergence of novel influenza A viruses.

Global spread of Salmonella Enteritidis

Nat Comm 2021, 12:5109 26 August, 2021 In the 1980s, simultaneous increase of Salmonella enterica serotype Enteritidis infections linked to poultry occurred in North America, South America, and Europe. By the late 1980s and the 1990s, Salmonella Enteritidis had spread to the poultry production systems in Asia and Africa. The pandemic subsequently declined in the late 1990s in the US and the United Kingdom (UK), but Salmonella Enteritidis remains a substantial problem for poultry production and public health.
Between 2015 and 2018, Salmonella Enteritidis contaminated eggs caused the largest known salmonellosis outbreak in Europe, resulting 1,209 reported cases in 16 countries. Decades after the inception of the pandemic, how the pathogen simultaneously increased in many parts of the world remained “a central and unsolved mystery”. Read More

Immunity and protection provided by live vaccines against Salmonella in poultry

Av Dis 65:295–302, 2021 24 August, 2021 Vaccination of poultry against paratyphoid Salmonella is a frequent strategy used to reduce the levels of infection and transmission, which ultimately can lead to lower rates of human infections. Live vaccines have been developed and used in poultry immediately after hatching as a result of their ability to colonize the gut, stimulate a mucosal immune response, induce a competitive inhibitory effect against homologous wild strains, and reduce colonization and excretion of Salmonella. Furthermore, vaccines can competitively exclude some heterologous strains of Salmonella from colonizing the gastrointestinal tract when young poultry are immunologically immature. In addition, various studies have suggested that booster vaccination with live vaccines a few weeks after initial vaccination is essential to increase the level ofprotection and achieve better cross-protective immunity.

Sweden: Increase cases of campylobacter

24 August, 2021 Since the end of July, the number of people infected with campylobacter has been high, with between 160 and 200 reported cases per week.
The increase has been seen throughout the country and in all age groups. The period has been preceded by an increased proportion of broiler flocks carried on campylobacter (Swedish Veterinary Institute (SVA). Read More

HPAI H5N8 and H5N1 outbreaks in GB: Nov. 2020 to Apr. 2021

DEFRA 18 August, 2021 The outbreak of high pathogenicity avian influenza virus in Great Britain from November 2020 to March 2021 consisted of two types of virus, H5N8 (twenty infected premises) and H5N1 (two infected premises). Infection was disclosed across England, Scotland and Wales in commercial layer and broiler flocks, small-holder flocks, game flocks, captive bird collections and birds of prey – including a conservation centre and two animal rescue centres. There was no apparent spatial nor temporal clustering of infected premises.
Extensive epidemiological, tracings and genome sequencing investigations revealed no evidence of spread between any of the infected holdings, neither within the United Kingdom, nor to trading partners. The only spread between infected premises occurred on one large holding, where the three separate premises were located in close proximity and were operated as one business that shared staff and equipment across the sites.

Reduction in antimicrobial use in broilers, Canada, 2013-2019

Emerging Infectious Diseases Vol 27, Number 9 - September 2021 9 August, 2021 A recent study provides data on antimicrobial use and AMR of foodborne bacteria (Salmonella, Escherichia coli, and Campylobacter) in broiler chickens during 2013 and 2019. Antimicrobial resistance (AMR) in broiler chickens declined by 6%–38% after the decrease in prophylactic antimicrobial use. However, the withdrawal of individual compounds, such as cephalosporins and fluoroquinolones, prompted an increase in use of and resistance levels for other drug classes, such as aminoglycosides.
The study shows that the injection of antimicrobials in ovo or subcutaneously at hatcheries is significantly associated with resistance in foodborne bacteria on the farm. Read More

New Zealand: Further testing programme to protect consumers

1 August, 2021 New Zealand Food Safety (NZFS) is extending a programme of testing to determine the extent of Salmonella Enteritidis (SE) in poultry flocks in New Zealand and to reduce the risk to consumers.
NZFS has been carrying out tracing and testing of poultry operations after SE was found at an Auckland poultry farm. These efforts have focused on egg producers. As a result, restrictions have been placed on three North Island egg layer operations, preventing potentially infected eggs from reaching consumers. The country's food safety body has expanded its testing programme for salmonella to include another 25 operations - which account for 80 per cent of eggs sold to the public. Read More

Denmark: Salmonella targets and surveillance in the poultry production 2020

1 August, 2021 - Two breeding flocks were positive for target serovars in 2020 with S. Typhimurium and S. Enteritidis. Thereby, 0.8% of the breeding flocks of G. gallus in Denmark were positive for target serovars (EU target for S. Typhimurium including the monophasic S. 1,4,[5],12:i:- variant, S. Enteritidis, S. Hadar, S. Infantis and S. Virchow is maximum 1%).
- No turkey flocks were positive with S. Typhimurium or S. Enteritidis in 2020 (EU target for Salmonella in breeding and fattening turkey flocks is 1% positive for S. Typhimurium or S. Enteritidis).
- In 2020 the prevalence for any Salmonella in laying flocks was 1.85%, as eight flocks (8/432) were found positive. Read More

Gross pathology associated with HPAI H5N8 and H5N1

Lean et al. (2021) Vet Rec. e731. 30 July, 2021 In a study published in Veterinary Record, researchers described the pathology among poultry species naturally infected with HPAIV between October 2020 and April 2021, that have occurred in the United Kingdom. On gross examination, pancreatic necrosis was easily identified and most commonly observed in galliformes infected with both subtypes of HPAIV (H5N8 and H5N1) but rarely in anseriformes. In addition, splenic necrosis was also frequently observed in chickens and turkeys infected with HPAIV H5N8. Other less common lesions included cardiac petechiae, serosal haemorrhages and ascites in a variety of species. Read More

FSA: Report into the sources of human Campylobacter infection published

27 July, 2021 The Food Standards Agency- UK, has published a study to further determine the principal sources of this foodborne disease. A report published by the FSA confirms that chickens are the source of the majority of human cases of Campylobacter, followed by other animals such as sheep, pigs and cows. This infection may have been passed to people directly through food, but could also be via environmental and water contamination.
The Campylobacter Source Attribution Study, launched in 2015 as part of the FSA’s wider and ongoing Campylobacter Reduction Programme, also reveals an increase in antimicrobial resistance within Campylobacter strains between 1997 and 2018. Around 300,000 human cases of Campylobacter are estimated to be acquired from food each year in the UK, out of a total of around 630,000 cases. Read More

Epidemiological situation of Campylobacter & Salmonella in Australia, 2016

17 July, 2021 Record levels of Campylobacter and Salmonella have been recorded in Australia, according to the annual surveillance report of notifiable diseases for 2016. Campylobacteriosis was the most frequently notified enteric infection in Australia in 2016. There were 24,164 notified cases of campylobacteriosis in 2016, making it the most frequently notified enteric infection (146.9 per 100,000 population). There has been a 7% increase onthe number of notifications received for 2015 (n= 22,549) and an increase of 33% on the previous five-year historical mean, 2011 to 2015 (n = 18,122). This rise may be associated with the increased use of culture independent diagnostic testing. Read More

Salmonella reports fall in Austria

17 July, 2021 In 2020, the number of primary human isolates sent to the National Reference Center for Salmonella (NRZS) decreased by 51.6% as compared to 2019. In 2020, 906 human salmonella isolates were recorded by the NRZS.
An annual incidence of 10.2 / 100,000 inhabitants.
Salmonella enteritidis was the most frequent serovar (43.4%) with 393 human isolates. S. typhimurium (including the monophasic variant) was the second most common serotype 166 cases (18.3%). Read More

Salmonella in Canada

Canada Communicable Disease Report (CCDR) 16 July, 2021 A new study shows that of the 96,082 Salmonella cases reported to the National Enteric Surveillance Program (NESP) in Canada during the 14-year study period,4.4% were bacteremic. Patients with bacteremia are more likely to experience severe outcomes, including hospitalization and death, unless treated promptly with antibiotics. 19 nontyphoidal Salmonella (NTS) serovars were identified as having higher rates of bacteremia. Of the 570 NTS serovars reported to the NESP from 2006 to2019, 136 were associated with bacteremia. Read More

FSIS: revised guidelines for controlling Salmonella and Campylobacter in raw poultry

13 July, 2021 The Department of Agriculture's (USDA) Food Safety Inspection Service (FSIS) announced the availability of revised guidelines to assist poultry establishments in controlling Salmonella and Campylobacter in raw poultry. The Agency has revised the content of the guidelines in light of new scientific and technical information, public comments received on the 2015 guideline, and the agency’s decision to issue two separate guidelines - one on controlling Salmonella and the other on controlling Campylobacter. Read More

Campylobacter in Sweden

5 July, 2021 Since 1997, the incidence of human campylobacteriosis in Sweden has varied between 65 and 110 cases per 100 000 inhabitants. Most cases are infected abroad, but in 2014–2018 the proportion of domestic infections increased due to several major outbreaks caused by domestically produced chicken meat. The COVID-19 pandemic has resulted in both a record low incidence of Campylobacteriosis and a record high proportion of domestic infections in relation to infections retrieved abroad in 2020.
The strong association between the prevalence of Campylobacter in broiler flocks and infections among humans makes monitoring in broiler flocks an important tool for early warning. The Swedish Poultry Meat Association has operated a monitoring programme for broiler chicken since 1991. The goal is to achieve an overall annual Campylobacter prevalence of less than 10% in slaughter batches of chicken. Read More

Salmonellosis in Sweden

5 July, 2021 Salmonella was not detected in any of the 4147 broiler flocks tested in routine sampling before slaughter. Salmonella was detected in 7 of the 646 flocks of layers tested. Salmonella was not detected in any breeding flocks, neither in any samples of commercially raised turkey flocks, quails, or ostriches. Salmonella was detected in one small-scale flock with laying hens, ducks and geese. It is estimated that approximately 20% of the poultry holdings lackan annual official sampling.Humans: In 2020, a total of 826 cases of salmonellosis were reported, compared to 1993 cases in 2019.

UK: Major retailers publish campylobacter results - Q1

19 June, 2021 The top nine retailers across the UK have published their latest testing results on campylobacter contamination in UK-produced fresh whole chickens (covering samples tested from January to March 2021). The Food Standards Agency (FSA) maximum acceptable level is 7 percent of birds with more than 1,000 colony forming units per gram (CFU/g) of Campylobacter.
The latest results, which cover January to March this year (Q1 of 2021), show that all nine supermarkets have achieved levels below this amount of heavy contamination. Similarly, the majority have recorded contamination levels that are lower than they did between October and December last year (Q4 of 2020). Read More

Campylobacter contamination in fresh whole UK produced chilled chickens at retail sale

19 June, 2021 Research published by the FSA has found the percentage of chicken sold at smaller retailers contaminated at more than 1,000 CFU/g is still higher than samples from supermarkets. The UK-wide survey looked at the levels of Campylobacter on whole fresh retail chickens on sale in farm shops and markets, butchers and smaller chains such as Iceland, McColl’s, Budgens, Nisa, Costcutter, and One Stop. A total of 1,009 fresh raw chickens were collected from August 2018 to July 2019.Campylobacter spp. were detected in 55.8% of the chicken skin samples obtained from non-major retailer shops, and 10.8% of the samples had counts above 1000 cfu per g chicken skin.

Eurosurveillance: data on H5N8 isolated from a Russian poultry worker

Eurosurveillance: Vol 26, Issue 24, 17/Jun/2021 19 June, 2021 In December 2020, the RNA of avian influenza A(H5N8) virus was detected in nasopharyngeal swabs taken from seven poultry workers during an outbreak at a large poultry farm in the Astrakhan region on the Volga River in southern Russia. An influenza A(H5N8) virus isolate was obtained from one human clinical specimen.
The outbreak of highly pathogenic avian influenza (HPAI) occurred at the Vladimirovskaya poultry farm located in Astrakhan region, Russia. The total flock size at the poultry farm was 924,612 chickens of all ages. On 3 December 2020, the first 750 chickens died and additional mortality was later observed at the site. All birds had the same symptoms (diarrhoea, conjunctivitis, haemorrhagic lesions of the respiratory and digestive tract). The Astrakhan Veterinary Laboratory preliminarily detected influenza A(H5) viral RNA in poultry tissue samples (lung, trachea, intestine, spleen) from a subset of 18 dead birds on 7 December 2020.

Avian influenza overview February – May 2021

9 June, 2021 A Scientific report from European Food Safety Authority (EFSA), published on May 31, 2021, describes the February-May 2021 European High Pathogenic Avian Influenza (HPAI) season as “one of the largest and most devastating HPAI epidemics ever occurred in Europe.” The 2020-2021 HPAI epidemic counts 3,555 detected infections in 27 European countries (22 EU MS, Norway, Serbia, Switzerland, Ukraine and the United Kingdom), involving 22.4 million poultry birds. The epicenter of the HPAI epidemic appears to have been in Germany and Poland, with the former country detecting the largest number of infections in wild birds (603) and the latter the largest number of outbreaks in farm flocks (297). During this period, sixteen different HPAI genotypes were found, indicating a high level of virus reassortment. Read More

First human case of H10N3 avian influenza

1 June, 2021 China's National Health Commission informed that the first case of human infection with the H10N3 strain of avian influenza from the country's eastern Jiangsu province has been reported. The patient, a 41-year-old man from Zhenjiang city, is currently in a stable condition and meets discharge standards. The man is from the city of Zhenjiang in Jiangsu province on China's east-central coast. His symptoms—nausea and fever—began on Apr 23. He was admitted to an intensive care unit on Apr 28, and he is currently listed in stable condition.
An investigation found no clear history of exposure to poultry, and no H10N3 had been detected in local poultry. No related infections were found in any of the man's contacts. Genetic analysis found that the virus is avian in origin. Read More

USDA recalls 65 tons of frozen chicken

29 May, 2021 The U.S. Department of Agriculture’s (USDA) Food Safety and Inspection Service (FSIS) has issued a public health alert for approximately 65 tons (130,860 pounds) of frozen fully cooked, diced chicken products because they may be contaminated with Listeria monocytogenes.
The problem was discovered during routine FSIS inspection activities when inspection personnel observed products requiring recooking due to possible L. monocytogenes contamination had been repackaged without being recooked. A subsequent FSIS investigation determined other affected product had been further distributed in commerce. There have been no confirmed reports of adverse reactions due to consumption of these products. Read More

The Netherlands: WBVR tests foxes positive for avian influenza (H5N1)

29 May, 2021 Wageningen Bioveterinary Research (WBVR) has diagnosed bird flu in two foxes from the province of Groningen in the Netherlands and characterized the viruses as H5N1. The sequences of the avian influenza viruses in the foxes are similar to those identified in infected wild birds from the same region. It is therefore likely that the foxes became infected from eating a bird infected with avian influenza. Avian influenza virus infections in foxes have been previously observed in other parts of the world and recently in England. Read More

22 May, 2021 China has reported an outbreak of H5N8 avian influenza in Nagqu City, southwest China's Tibet Autonomous Region. The highly pathogenic disease has been detected among wild birds in two areas of Nagqu, including a national wetland park. So far, 268 wild birds have been infected and killed.
South Africa: Approximately 134,000 chickens have died or been culled in the Western Cape as a result of a avian influenza outbreak affecting the province. Avian influenza (H5N1), has been detected at four poultry farms in the Western Cape so far. The infected farms are situated near Worcester, Malmesbury, and Hopefield. An avian influenza outbreak was first detected in Gauteng last month where at least two farms in the East Rand have been affected. Read More

Salmonella Infantis in Dutch broiler flocks

Veterinary Microbiology 258 (2021) 22 May, 2021 Since 2014, S. Infantis has been the most commonly isolated serovar in broilers in the Netherlands, accounting for 78% of all Salmonella isolates from broilers reported in 2018. Also Europe-wide, S. Infantis is currently the most common serovar in broilers (46–57 %) and broiler meat (37–51 %),and its prevalence has increased in breeding flocks as well. Moreover, S. Infantis ranked fourth among the serovars isolated from human salmonellosis cases in the Netherlands and in Europe in the past few years, after S. Enteritidis, S. Typhimurium and its monophasic variant. In 2014, a multi-drug resistant S. Infantis strain was identified in Israel carrying a mega-plasmid of approximately 300 Kb named pESI (plasmid of emerging S. Infantis). Read More

Organic meat less likely to be contaminated with multidrug-resistant bacteria

14 May, 2021 Meat that is certified organic by the U.S. Department of Agriculture is less likely to be contaminated with bacteria that can sicken people, including dangerous, multidrug-resistant organisms, compared to conventionally produced meat, according to a study from researchers at the Johns Hopkins Bloomberg School of Public Health.
The researchers found that, compared to conventionally processed meats, organic-certified meats were 56% less likely to be contaminated with multidrug-resistant bacteria. The study was based on nationwide testing of meats from 2012 to 2017 as part of the U.S. National Antimicrobial Resistance Monitoring System (NARMS). A longstanding concern about antibiotic use in livestock and livestock feed is the increased prevalence of antibiotic-resistant pathogens. Read More

CDC: Increased incidence of resistant Salmonella infections

Emerging Infectious Diseases Vol 27, Number 6 June 2021 13 May, 2021 In a study published in Emerging Infectious Diseases, the researchers estimated a 40% increase in the annual incidence of nontyphoidal Salmonella infections with clinically important resistance in 2015-2016 compared with 2004-2008. When extrapolated to the entire US population, that amounts to roughly 63,000 more infections a year caused by antibiotic-resistant Salmonella.
During 2015–2016, the mean annual incidence was 2.38 (95% CrI 1.93–2.86)/100,000 persons for clinically important resistant infections and 1.83 (95% CrI 1.45–2.25)/100,000 persons for MDR infections. Read More

Japan: avian influenza has almost ended

10 May, 2021 The outbreak of highly pathogenic avian influenza in Japan has almost ended after having swept across the country from last November.
This season, avian influenza was discovered in 18 prefectures, including Chiba and Ibaraki, which are known for poultry farming.
The number of chickens and ducks that were culled this season in order to prevent the further spread of infections stood at around 9.87 million, up drastically from the previous record high of some 1.83 million such birds put down between the autumn of 2010 and the spring the following year.

Salmonella Bareilly and egg powder

Eurosurveillance Volume 26, Issue 14, 08/Apr/2021 1 May, 2021 In August 2017, the number of human S. Bareilly cases reported in the Czech Republic exceeded the maximal annual total number of cases from the previous 5 years (n = 25). The State Veterinary Administration (SVA) identified a Salmonella Bareilly isolate closely related to human outbreak isolates in a powdered egg product called dried egg melange. This led to the agency investigating the company making the powdered egg and inspections at farms that produced eggs for further processing. The first confirmed Salmonella Bareilly patient had disease onset in July 2017. The number of infections peaked in October 2017, and the last confirmed patient was reported in October 2018. In total, 250 probable cases were identified in the Czech Republic and 75 in Slovakia. Two small peaks were observed in Slovakia in October 2017 and April 2018. Read More

EU: Antimicrobial Resistance in zoonotic bacteria 2018-19

20 April, 2021 Data on antimicrobial resistance (AMR) in zoonotic and indicator bacteria from humans, animals and food are collected annually by the EU Member States (MSs), jointly analysed by the EFSA and the ECDC and reported in a yearly EU Summary Report.
A sizeable proportion of Salmonella and Campylobacter bacteria is still resistant to antibiotics commonly used in humans and animals, as in previous years, says a report released by the European Centre for Disease Prevention and Control (ECDC) and the European Food Safety Authority (EFSA). In humans, high proportions of resistance to ciprofloxacin, an antibiotic commonly used to treat several types of infections, were reported in a specific Salmonella type known as S. Kentucky (82.1%). In recent years, S. Enteritidis resistant to nalidixic acid and/or ciprofloxacin has been increasingly reported in several countries. Read More

Ireland: use of unauthorised antibiotics in poultry flocks

17 April, 2021 More than 60,000 chickens have been destroyed at an Irish meat processor after tests identified the birds may have been reared using unauthorised antibiotic growth promoters.
Carton Bros, Ireland’s largest poultry processor, have said routine tests raised the possible use of unauthorised antibiotics. As a result, 60,000 birds were rendered, with tens of thousands more placed in cold storage until testing was completed over fears too that they were not fit for human consumption. Read More

South Africa: Newcastle disease in wild birds

14 April, 2021 Birds found dead, mostly doves, in parts of the Eastern Cape have died of Avian Paramyxovirus and Newcastle diseases. The Eastern Cape department of Rural Development and Agrarian Reform confirmed the test results on Tuesday (13/4).
Hundreds of bird deaths have been reported in the Buffalo City Municipality since March, which prompted Neville’s Snake and Reptile Rescue to collect dead birds for testing at the SPCA. Wild birds found mysteriously dying in Gqeberha were also handed to state veterinarians for testing.
Testing and investigation included tracing of birds, collecting and conducting post mortems to identify the cause of bird deaths. Samples collected were sent to the Onderstepoort Veterinary Research (OVR) Laboratory for analysis. Read More

UK: Avian influenza H5N8 strain detected in seals and fox

18 March, 2021 Carcasses of four common seals, one grey seal and one red fox submitted to APHA laboratory during December 2020 for diagnostic PME as part of routine wildlife disease surveillance activities. Two of the Common Seal carcasses were autolysed so were safely disposed of without PME. Following histopathological examination of tissues from the fox and seals identified lesions indicative of acute systemic viral infection further laboratory testing was performed at APHA. This testing resulted in the detection of H5N8 influenza virus infection. Gene Sequencing identified this H5N8 influenza virus to be [99.9%] identical to avian-origin H5N8 viruses detected from the Mute swans that had died and been tested from this wildlife rescue centre. In November 2020, five wild Mute swans (Cygnus olor) that had been rescued and taken to a wildlife rescue centre died, were tested and found to be infected with H5N8 HPAI. Read More

Campylobacter bacteria can exchange genetic material

Plos One, Feb. 11, 2021 19 February, 2021 Campylobacter is the worldwide leading cause for foodborne illness and it persists throughout poultry production, from farm to grocery shelves. According to new research, two of the most common strains are exchanging genetic material.
Campylobacter bacteria spread primarily through consumption of contaminated food products. There are two strains of Campylobacter that we’re concerned with:
C. coli and C. jejuni.
C. jejuni causes up to 90% of human Campylobacter infections, but this strain is less likely to carry multidrug-resistant genes. C. coli is twice as likely to contain multidrug-resistant genes, but it’s a less effective human pathogen. Read More

Presence of Salmonella in chicken meat from conventional and without antibiotic-related claims

International Journal of Food Microbiology 2021 16 January, 2021 Antimicrobial resistance (AMR) in non-typhoidal Salmonella from poultry is a public health concern. Injudicious use of antibiotics in humans and agriculture fuels the emergence of resistance. The objective of a new study was to characterize the prevalence, antibiotic susceptibility profiles and genetic resistance mechanisms of Salmonella isolated from US retail poultry meat samples with and without antibiotic-related claims. The study reviewed data from 46,937 poultry meat samples collected from 2008 to 2017 through the FDA NARMS retail meat program. Antibiotic usage claims on the poultry packaging were used to categorize the sample as 'conventionally raised' or 'reduced or no antibiotic use'. The results show that the prevalence of Salmonella in conventional poultry samples (8.6%) was higher than reduced or no antibiotic use poultry samples (5.1%). The odds of MDR≥3 were 2.61 times higher for Salmonella isolates from conventional samples, compared to isolates from redu Read More
