A quick look back: There have been a number of bird flu cases across the country in recent weeks.

  • Highly lethal bird flu outbreaks have been found in Kentucky and Virginia, as I wrote for the Deseret News. This directly put some chicken linked to Tyson Foods in danger. The infected birds were culled, stopping the food from entering the food system.
  • There were also confirmed cases in Indiana, per Reuters.

The bottom line: So far, it seems like bird flu cases are spreading throughout the country. However, avian influenza does not pose a threat to humans.
