Chemistry - Residue Analysis

Residue chemistry guidelines monitor the safety of chemical use in human food and animal feed, and attempt to assess the dietary risks associated with chemical use. While residue chemistry is a critical element to chemical and pesticide registration, its data includes far more than information on the magnitude of residues in crop commodities. TSG’s scientists have years of experience designing, monitoring, reporting and defending metabolism, residue, environmental fate and transport studies to meet world-wide regulatory requirements. We have expertise in method choice and data review for any project that involves chemical measurements, beginning at the definition phase and continuing through sampling, analysis and reporting.

Our consultants have broad experience and a varied perspective in developing residue chemistry data that not only meets specific guidelines, but directly addresses the regulatory concerns on which guidelines are based.

We assist in the following:

▲ Determining the nature of the residue studies in crops and, if applicable, in livestock;

▲ Ensuring stability of field-incurred residues during storage prior to analysis;

▲ Validating analytical methods with incurred radio-labeled residues;

▲ Determining residues in water, fish and irrigated crops, confined and field rotated crops, and processed commodities; and

▲ Determining residues resulting from use of
pesticides in food-handling establishments.

If necessary, we can respond to agency concerns regarding the conduct and outcome of required studies used to support information on the concentration of residues in crop and livestock commodities.
