The economic value of the H7N9 vaccination program in poultry in Guangxi - China

Preventive Veterinary Medicine 200 (2022) 105580 17 January, 2022 Influenza A (H7N9) virus was first isolated from humans in March 2013 in China. It has also been detected in poultry in China in the same month and since then has spread across the country. China launched a series of policies to control the disease since April 2013, including:
(1) a disease surveillance programme in poultry; (2) closing live bird markets (LBMs) and controlling the movement of live poultry when infection in people or poultry were reported; (3) improving biosecurity of LBMs; and (4) the promotion of poultry meat trade to consumers over live bird value chains. Despite these interventions, there was only partial compliance with these measures. Highly pathogenic strains of H7N9 virus have been detected in humans and poultry since January 2017, posing an increased threat of infection.
China launched a H7N9 vaccination program in poultry, starting from the Guangxi and Guangdong provinces inJuly 2017, followed by other provinces in September 2017, as a response to a steep in Read More

China: Salmonella outbreak linked to eggs

Front. Microbiol., 22 November 2021 16 January, 2022 A Salmonella outbreak linked to egg fried rice in China affected more than 220 people this past year. The outbreak occurred in Beijing in March 2021 with 225 of 324 diners who ate at a canteen showing gastrointestinal symptoms. Epidemiological investigations and lab tests confirmed the outbreak was related to undercooked egg fried rice. Salmonella enteritidis was recovered from eggs. So the contaminated egg fried rice may be related to raw eggs carrying S. enteritidis. Read More

European AI viruses to cross the Atlantic to North America

bioRxiv preprint doi: 16 January, 2022 On December 20, 2021, the Canadian Food Inspection Agency (CFIA) confirmed the presence of HPAI subtype H5N1 at a multi-species exhibition farm in the Avalon Peninsula of Newfoundland and Labrador, Canada.
Highly pathogenic avian influenza (HPAI) viruses of the A/Goose/Guangdong/1/1996lineage (GsGd), which threaten the health of poultry, wildlife and humans, are spreading across Asia, Europe and Africa, but are currently absent from Oceania and the Americas. In December 2021, H5N1 HPAI viruses were detected in poultry and a free-living gull in St. John’s, Newfoundland and Labrador, Canada. Phylogenetic analysis showed that these viruses were most closely related to HPAI GsGd viruses circulating in northwestern Europe in spring 2021. Read More

The Norwegian Zoonoses Report 2020

10 January, 2022 Salmonellosis: The number of reported cases of salmonellosis in humans (440) decreased in 2020 compared to the previous four years. The surveillance programme for Salmonella includes testing of live animals (pigs, poultry and cattle) and fresh meat (pigs and cattle). From altogether 8,882 faecal samples in 1,342 poultry holdings one broiler flock was positive for Salmonella, giving an estimated Salmonella prevalence of 0.02% in poultry flocks for slaughter. The number of salmonellosis cases in humans has decreased over the past 10 years. The number of cases infected in Norway has remained relatively stable with an incidence of 3.6 to 6.1 in the last 5 years (2015- 2019) but decreased to 3.2 in 2020, probably due to measurements against COVID-19 in Norway. The reduced prevalence of Salmonella in European poultry is presumed to contribute to the observed reduction. Read More

First report of avian infuenza in Spain

8 January, 2022 The HPAI H5N1 strain has now hit Spain. The influenza virus was detected in four swans and a stork that were found dead in the Segre river in Lleida, Catalonia.
For now, the National Avian Influenza Surveillance Programme in Spain has decreed that the outbreak should not lead to commercial restrictions on the movement of live birds or their products. Read More

A case of avian influenza in a person in the South West of England

6 January, 2022 This is clearly going to be big news but the key thing is that human infections with H5N1 are really rare (fewer than 1000 worldwide since 2003) and they almost always occur as a result of direct, long term contact with poultry. The case was detected by officials swabbing people who had close contact with infected flocks. Laboratory analysis revealed the virus was the 'H5N1' type found in birds. The person (79-year-old Alan Gosling, a retired engineer) acquired the infection from very close, regular contact with a large number of infected birds (ducks), which they kept in and around their home over a prolonged period of time.

Second case of avian influenza in Canada

3 January, 2022 Environment Canada says a highly pathogenic avian influenza first identified on a farm on the Avalon Peninsula has been found in birds around the St. John's area.
Environment Canada had confirmed the H5N1 virus, has been found in wild birds in areas like Bowring Park, Quidi Vidi Lake and other areas frequented by flocks of birds.
Cases of H5N1 were first identified on the island around mid-December on an exhibition farm on the island. Read More
