The BEEF Act would suspend a recent presidential order that expanded foreign beef imports and prevent future presidents from increasing beef imports without congressional approval. The legislation would require any executive action to expand beef imports to be submitted to Congress and receive specific statutory authorization within 30 days to take effect. The bill also establishes a Beef Import and Domestic Supply Advisory Board within the Department of Agriculture, composed of the Secretary of Agriculture and 11 members representing ranchers, livestock experts, processors, and consumer advocates, tasked with developing strategies to rebuild cattle herds, increase domestic beef production, reduce regulatory burdens on ranchers, and keep beef affordable. The advisory board would operate for four years from the bill's enactment and would provide policy recommendations to the Secretary of Agriculture and Congress on expanding domestic processing capacity and improving competition in livestock markets.
