Pribylova et al. report finding MaP bacteria in intestine (used for sausage casings), masseter (chewing muscle) and diaphragm of dairy cattle. They state that "due to the changing behaviour of consumers, both of these muscles have started to be widely used in cuisine" and suggest that "processing of cows with paratuberculosis in abattoirs without any precautions (restrictions) and the usage of meat for human consumption should be rethought."
Münster et al. report finding about 17% of a random sample of German cattle MaP positive.

High levels of aflatoxin M1 have been found in a batch of milk before release for sales by China Mengniu Dairy Group and created a new scare, following the contamination of milk with melamine in 2008.
A new virus has been detected in Germany and The Netherlands and is suspected to be the cause of disease and abortions in cattle and sheep. The virus has been called Schmallenberg virus (SBV) preliminarily, after the German city where the identified strain was sampled. The risk for humans seems to be low, but significant uncertainties exist.
The debate as to who should pay for food safety is a good one to have as it indicates that the problem has moved from the technological to the economic level. This may not be entirely the case with Shigatoxin-producing E. coli, but it is good to learn about advances in this field.

High prevalence of Mycobacterium avium subspecies paratuberculosis (‘Indian bison type’) in animal attendants suffering from gastrointestinal complaints who work with goat herds endemic for Johne's disease in India25 November 2011 | Technical news (commented)

Journal of Infectious Diseases; Volume 15, Issue 10 , Pages e677-e683, October 2011
"Conclusions: The prevalence of MAP was higher in attendants suffering from gastrointestinal problems who worked with goat herds endemic for Johne's disease, than in humans with no history of contact with animals. The risk of developing gastrointestinal problems with clinical symptoms indistinguishable from inflammatory bowel disease was higher in humans who were in contact with goat herds endemic for Johne's disease as compared to healthy humans, and the risk was correlated with the duration of association with the endemic goat herds."

T. Seuberlich et al. (including our member D. Heim) report about the finding of a novel prion protein in two BSE-affected cattle. In April and May 2011, two cows were found BSE-positive by Western Blotting. Their PrPres phenotypes falls in none of the three previously described categories, C-BSE, H-BSE or L-BSE.
The significance of this finding is unclear.
