Naproxen-OVA Antigen

Naproxen is a non-steroidal anti-inflammatory drug (NSAID) used to alleviate pain, fever, and inflammation. While predominantly a human medication, it is sometimes used off-label or illegally in veterinary practice to treat musculoskeletal disorders and inflammatory conditions in food-producing livestock like cattle and swine. Its relevance to food safety stems from the risk of illegal residues transferring into milk, meat, and tissues if proper withdrawal periods are not followed. Because human exposure to unexpected NSAID residues can trigger adverse reactions-such as gastrointestinal bleeding, renal hypersensitivity, or allergic responses-regulatory agencies strictly monitor and enforce zero-tolerance or low maximum residue thresholds for naproxen in animal-derived matrices.
