Application of an enzyme-linked immunosorbent assay (ELISA) to determine paraquat residues in milk, beef, and potatoes
The USDA Food Safety and Inspection Service (FSIS) has included paraquat on its list of compounds to be considered for monitoring in foods. However, present methods do not easily accommodate the processing of large numbers of samples, thus limiting routine monitoring of the compound. The conventional method, based on spectrophotometry of reduced paraquat solutions, requires time-consuming sample preparation. Although the advantages of immunoassays for pesticide residue analysis have been pointed out, the reported immunoassays for paraquat have only been applied to cases of clinical poisoning or human exposure assessment. In this study, spiked milk, potato, and beef were analyzed directly, without prior cleanup, by an enzyme-linked immunosorbent assay (ELISA).
