FDA Proposes More Pet Food Regulations

Though it still doesn't know why some jerky treats are currently killing dogs

Amid incidents of pets dying from dog treats, the Food and Drug Administration is proposing long-awaited rules to make pet food and animal feed safer.

The rules stem from a sweeping food safety law passed by Congress almost three years ago. Like rules proposed earlier this year for human food, they would focus on preventing contamination before it begins.

The announcement comes as the FDA says it hasn't yet determined a cause of almost 600 dog deaths believed to be linked to pet jerky treats imported from China. The agency has been trying for six years to determine what exactly is causing those illnesses.
