Expanded Food Safety Investigation Act of 2025

This bill allows the FDA to request microbial sampling at large livestock facilities (concentrated animal feeding operations or CAFOs) during foodborne illness outbreaks to identify causes and protect public health. CAFOs must grant "reasonable access" for sampling of animals, plants, water, and the environment, though they can specify timing and location to avoid disruption. The law clarifies it does not impose new requirements beyond sampling for USDA-regulated foods (like meat or poultry) and requires sharing collected data with the USDA and public health agencies. It directly affects CAFOs and federal food safety agencies, focusing on outbreak response mechanisms.
