The FDA this week released a new Compliance Policy Guide (CPG) regarding salmonella contamination in food for animals, creating a zero-tolerance standard for pet foods and a less-stringent risk-based standard for livestock feeds.

Pet foods contaminated with salmonella pose a higher risk to human health due to the more frequent direct contact pet owners have with those products.

For livestock and horse feeds, the CPG outlines a risk-based salmonella enforcement policy, focusing on the strains that are capable of causing disease in animals, and provides examples of salmonella strains reported to cause disease in a specific animal species such as Salmonella Newport or Salmonella Dublin in dairy or beef feeds.
