Tunisian Clams contaminated with Hepatitis A Virus
Italy recently alerted the EU through the RASFF (Feb. 18th) on a Hepatitis A Virus contamination of Tunisian clams. Clams have often be implicated in viral contamination as previously reported on this blog (http://ceeram.blogspot.fr/2015/07/rasff-foodborne-virus-annual-report-2014.html), especially in 2014 with vietnamese clams contaminated by norovirus.
4 Hepatitis A Virus alerts in 2 days
On February 19th, Italy posted 3 more alerts on clams imported from Tunisia. Destruction was the fate of those clams (Ruditapes decussatus).
Monitoring viruses (norovirus, hepatitis A Virus) in mollusks
In our May 13th, 2010 article (http://ceeram.blogspot.fr/2010/05/studies-suggest-benefits-of-monitoring.html) we were echoeing a study from CIDRAP, where the group concluded :
- that growing evidence suggests that it is possible to gauge illness risk based on norovirus levels in oysters and that given the inadequacy of existing controls to prevent contamination,
- that setting an appropriate virus standard would yield public health benefits.
- that validated treatment processes can be used to produce a safe product, even when low levels of norovirus are detected in the treated oysters.
