About Us

Founded in 1977, Diversified has over 40 years of experience protecting our customers by analyzing and detecting pesticides, PCB's, chlorinated dioxins, chlorinated hydrocarbons and other chemical contaminants in food and animal feed products. Pesticides are highly persistent in the environment and are readily stored and concentrated in poultry and livestock tissues and therefore represent a concern for human health.

The dangerous nature of these industrial chemicals requires constant vigilance at all levels, from the the corporate arena to federal, state and local governments. EPA has established tolerances for these chemicals and the FDA and USDA have responsibility to enforce them, but our customers bear the burden of compliance to insure a safe product. The potential economic consequences of a contamination, if left undetected, can readily exceed $1 million.

Diversified Laboratories makes it as easy and convenient for our customers to insure safe products for themselves and their customers with quick, accurate and confidential testing. By using Diversified as part of an ongoing quality assurance program our customers are insured against potential problems with rapid detection and reporting. Our approach has helped preserve a perfect record of no FDA/USDA involvement for over 40 years.
