Food Contaminants

Food ContaminantsAssuring the purity of ingredients and products is paramount in the NFL’s Food Contaminant program. With a clear understanding of U.S. and international food contaminant issues, we work with you to put together meaningful programs. Our chemists are leaders in the industry and continuously review the trends and technologies in the industry so that we can offer the best, most relevant programs for our clients. Our new Signature Screen leverages new technology, enabling us to identify residues at lower detection levels than other screening methods. It identifies 35 pesticides that have emerged in the global market in recent years. Combined with our Multi-Residue Analysis of 198 compounds, The NFL offers the most up-to-date and robust food contaminant testing available.
