About Us

Wil A. Sumner, B.S., M.S.

Experience

I have 29 years experience of providing testing, consulting, and certification services to Agriculture, Food Processing and Retail Food Industry. My career has provided me with substantial knowledge of state & federal pesticide laws (Federal Insecticide Fungicide, & Rodenticide Act) , Food & Drug laws (Food Drug & Cosmetic Act, FD&C Act)  dealing with chemical and microbiological adulteration of foods.  I am familiar with current regulations on the operation of chemical and microbiological testing labs pertaining to pesticide residue analysis, monitoring technology of chemicals, toxicology, pathogen testing, all dealing with agricultural production.

Due to the increasing number of new pesticides and formulations our task is to also design new testing protocols and sampling methods, to expedite the testing services yet all within the bounds of ISO 17025. I also conduct risk assessment models for pesticide residues and other chemical contaminates in foods for submission to EPA, POP.

Our risk assessment work is and has been used for the National Academy of Sciences in their assessment of pesticide residues in foods. We also work with international organizations for the development of pesticide risk models for the World Health Organization, Nicaragua Ministry of Health, Guatemala Dept of Agriculture, Honduras Research Institute, Health & Welfare Canada, and  Taiwan National Toxics Lab.

I am a former federal food scientist with training in FDA Law as an expert witness.  I have served on cases involving pesticide (fumigant) exposure to humans, adulteration of crops to pesticides due to drift, adulteration of produce and processed foods with pathogens, adulteration of foods and produce with heavy metals, adulteration of foods due to lack of process controls, adulteration of foods due to chemicals in distribution, etc.
