Australia: Raw egg warning after 70 contract Salmonella

6 February, 2017 Salmonella outbreaks in five locations across the state has prompted a warning to Queenslanders to stop playing Russian roulette with uncooked eggs and meat.
Health Minister Cameron Dick said more than 70 people were infected by the five outbreaks of the food-borne bacteria, which can lead to death in those with weakened immune systems. “While eggs are a great source of protein and are important for a healthy diet, if you eat them raw or undercooked, you really are playing Russian roulette with your health,” Mr Dick said.
The Minister said three of the current outbreaks across the State have been linked to more than 30 confirmed cases from raw or undercooked egg in Brisbane, while a further 37 people were infected after consuming undercooked pork in Mount Isa. Around 5000 cases of Salmonella are reported in Queensland each year. Chief Health Officer Dr Jeanette Young said the rate of Salmonella infection in Queensland is concerning. Read More

Germany: HPAI H5N2 Detected In WIld Birds In Baden-Württemberg

Source: Avian Flu Diary 30 January, 2017 One of the hallmarks of Clade H5 viruses (which include both H5N8 and H5N6 subtypes) has been its enhanced ability to successfully reassort with other (mostly LPAI) viruses it encounters in its travels, and in doing so spinning off new genotypes, and occasionally, new subtypes as well.
Although nearly all of the reports during the fall of 2016 were of H5N8, in December several nations (Italy, The Netherlands, and Montenegro) reported the discovery of a new HPAI H5N5 reassortant virus in a small number of wild birds. A week ago - and for the first time in Europe - HPAI H5N5 Was Detected In A German Poultry Operation. Three days later HPAI H5N5 Was Detected At Two More Poultry Farms. Read More

A(H5N8) Clade Viruses, Germany, 2016

EID, Vol. 23, No. 4 - April 2017 6 January, 2017 In late May 2016, a group B clade H5N8 virus was detected in dead and hunted wild birds at Lake Uvs-Nuur, at the Russia–Mongolia border. On November 7, 2016, many dead tufted ducks (Aythya fuligula) were found at Lake Plön in Schleswig-Holstein, northern Germany, and at Lake Constance in Baden-Württemberg, southern Germany; most were positive for H5N8.

Newcastle Disease: the titer needed to protect commercial layers

Research in Veterinary Science 111 (2017) 63–66 4 January, 2017 Newcastle disease virus (NDV) infection causes serious problems in laying chickens, like reducing egg production, increasing rate of abnormal eggs in spite of strict vaccination in layer farms program. A new evaluation system is needed to show complete protection of the immunization in laying chickens based on the egg-laying performance, rather than clinical signs of the disease.
In a study, by a group of Chinese researchers, laying chickens with different anti-NDV HI (hemagglutination-inhibition) antibody titer after vaccination were divided into different groups. These chickens were then challenged with field isolated highly virulent NDV strains. Read More

Risk Anal. 2016 36(3):561-70 2 January, 2017 Salmonellosis is a significant cause of foodborne gastroenteritis in Australia, and rates of illness have increased over recent years.

Avian Influenza A(H5N8), clade in wild aquatic birds, Russia-2016

EID, Vol. 23, No. 2 - February 2017 1 January, 2017 Highly pathogenic avian influenza virus (HPAIV) subtype H5N1 was first isolated from a goose in 1996 in Guangdong China (Gs/GD). This virus evolved into multiple hemagglutinin (HA) genetic clades and underwent reassortment with different neuraminidase and internal genes to generate subtype H5N8 clade Gs/GD HPAIV, which first appeared in an outbreak in poultry in China in 2013, followed closely by outbreaks in South Korea in January 2014. During these outbreaks, 2 distinct groups of H5N8 viruses were identified; group A (Buan-like) and group B (Gochang-like). There have been no further reports of group B virus since its original detection in China and South Korea during 2014. In contrast, in early 2014, group A viruses predominated in South Korea. On the basis of aquatic bird migration patterns, it is hypothesized that HPAIV (H5N8) reached Siberia during the 2014 spring bird migration. Read More
