Pesticide and Toxic compund Testing


Purity specializes in testing nutraceutical ingredients for toxic compounds in order to comply with all FDA guidelines.


In the nutraceutical industry, the ingredients most vulnerable to pesticide contamination are those that originate in the ground, such as minerals, organic ingredients, botanicals and herbs. Nutraceuticals can also absorb toxic compounds from exposure to chemicals used to clean machinery or from storage or handling areas where chemicals have been used.


There is a growing need for pesticide testing in the food industry. The American Academy of Pediatrics points to food as the primary source of children’s exposure to pesticides. Pesticides are widely used in food production in order to control pests such as insects, rodents, weeds, bacteria, mold and fungus. Even organic farmers are allowed to use approved pesticides listed in the National List of Allowed and Prohibited Substances and per applicable state regulations.


Purity has been testing products for the food industry for more than 45 years. In addition to pesticide testing, we provide a full range of food testing services including:


  • Food Allergens

  • Gluten

  • Authenticity

  • Contaminants

  • Microbiology

  • Nutritional

  • Filth & Extraneous Matter

  • GMO

  • Stability & Shelf Life

  • Heavy Metals Testing

  • Residual Solvents

  • Vitamins

  • Pathogens

  • Amino Acid

  • Proximate Testing


No other testing laboratory has the experience and the range of tests for the presence of pesticides (and other toxic chemicals) that Purity offers.


Purity is accredited to ISO/IEC 17025:2017 standards to provide our customers with the most accurate testing results.


Purity uses GC/MS technology to screen for hundreds of toxic chemicals that include pesticides, fungicides, insecticides, rodenticides, herbicides, biocides, endocrine disruptors and other toxic chemicals. Our state-of-the art GC/MS equipment and pesticide database can detect more than 900 toxic compounds in one sample using our comprehensive pesticide and toxic compounds panel.


If toxic compounds are detected, the sample will be processed for further quantification analysis to determine how much of the toxic compound is present. (Note:  Our 900+ toxic compound screen is in redevelopment as part of our Purity Gold Seal Program.  The expected date of completion is February 2023.)
