[FONT=&quot]Update on Avian Influenza[/FONT]

[FONT=&quot]On March 4, 2017, the National Veterinary Services Laboratory (NVSL) confirmed low pathogenic avian influenza (LPAI) in a commercial turkey flock owned by Jennie-O Turkey Store in Wisconsin. This situation in Wisconsin only involves one farm site where experienced flock management personnel identified health issues in the flock and promptly pursued testing.[/FONT]

[FONT=&quot]The strain is an H5N2 influenza of North American wild bird lineage. It?s important to understand that low path avian influenza is common in North America.[/FONT]

[FONT=&quot]There has also been a confirmed report of a highly pathogenic avian influenza (HPAI) of an ?H7? origin in a chicken breeder flock in Tennessee.

This HPAI situation does not involve Jennie-O Turkey Store and we have no turkey flocks in that area of the country.[/FONT]
[FONT=&quot]Poultry is safe to eat and products produced in the U.S. are safe for consumption. Avian influenza is an animal health issue, not a food safety issue. As a reminder, poultry and eggs should always be handled properly and cooked to an internal temperature of 165 ˚F. See the Food Safety section on this web site for more information.[/FONT]
