FDA proposes expanding loophole to allow toxic chemicals in food without safety review

The FDA is proposing to broaden its 'threshold of regulation' exemption, which currently permits non-carcinogenic toxic chemicals in food contact materials at levels below 0.5 ppb without review, to allow direct addition to food. Experts are alarmed, citing potential public health risks. The proposal marks a regulatory shift that could weaken food safety oversight, though its final scope and implementation remain uncertain.
