No H1N1 Flu Virus Found in Pork

16 February 2010

US - Pork from pigs infected with the pandemic influenza A H1N1 infected pigs is safe to eat, according to ARS research.

Vincent from the USDA Agricultural Research Service in Ames, Iowa and other have published a paper on the safety of meat from H1N1-infected pigs for human consumption. The paper was published in PLoS ONE.

The say that the emergence of the pandemic 2009 H1N1 influenza A virus in humans and subsequent discovery that it was of swine influenza virus lineages raised concern over the safety of pork.

Pigs experimentally infected with pandemic 2009 H1N1 influenza A virus developed respiratory disease; however, there was no evidence for systemic disease to suggest that pork from pigs infected with H1N1 influenza would contain infectious virus.

These findings support the WHO recommendation that pork harvested from pandemic influenza A H1N1 infected pigs is safe to consume when following standard meat hygiene practices.
