FDA Clarifies Animal Food Regulations In Supplemental Rulemaking

The Renewable Fuels Association (RFA) submitted comments to the Food and Drug Administration (FDA) last night on its supplemental rulemaking proposal outlining best practices for the regulation of animal food under the Food Safety Modernization Act.

In March, RFA submitted comments following the initial proposed rule noting that animal feed would be unnecessarily regulated in a similar fashion to human food. RFA praised the FDA for addressing this concern in its updated version, noting that the “revised CGMPs (current good manufacturing processes) in the supplemental proposed rule appear more applicable to the animal feed industry and appear to provide more flexibility for the wide variety of the animal feed facility processes covered.”
