Many countries have established regulatory standards to limit aflatoxin exposure. These regulations set maximum allowable levels of aflatoxins in food and feed products. For example, the U.S. Food and Drug Administration (FDA) has set action levels for aflatoxins in different food commodities, ranging from 20 parts per billion (ppb) for most foods to 0.5 ppb for milk. International organizations like the Codex Alimentarius Commission also provide guidelines and standards to ensure food safety and protect public health.
