Lamont et al. report observing MaP cultures going into a 'spore-like morphotype' under stress conditions. This has important implications for strategies to control MaP.
Long awaited, a key reference in our 'Recommended Risk Management Plan for Paratuberculosis' has finally become available online. You can find the paper 'Assessment of Sources of Exposure for Mycobacterium avium subsp. paratuberculosis in Food and Water' by Mihajlovic et al. in Int. food risk anal. j., 2011, Vol. 1, No. 2, 1-22, here. The paper represents another compilation of studies on MAP in food and water.
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.
