Pesticide program. Residue monitoring 1993. Food and Drug Administration.

A total of 12,751 samples of domestically produced food from all 50 states and Puerto Rico and imported food from 107 countries was analyzed for pesticide residues in 1993. Of these, 12,166 were surveillance samples, which are collected when there is no evidence of a pesticide problem. No residues were found in 64% of the domestic surveillance samples and 69% of the import surveillance samples. Findings in the 585 compliance samples reflect the fact that they are collected and analyzed when a pesticide problem is suspected. Under incidence/level monitoring, 308 samples of aquaculture seafood/shellfish and 308 milk samples were analyzed for pesticide residues. The findings were similar to those from FDA's regulatory monitoring. In addition, a statistically based monitoring survey of pears and tomatoes was completed in 1993. Low violation rates were found for both the domestic and import segments of the 2 commodities. The types of residues found in the Total Diet Study for 1991-1993 were similar to those found in earlier periods.
