Pesticide Residue Analysis Program

Occasionally when FDA pulls samples at the border and finds pesticide residues, your product or ranch will be put on FDA Import Detention without Physical Examination. Call PrimusLabs and we will be able to pull the samples and conduct the analysis needed to get you back in business as soon as possible.

A “Certified” program is a pre-harvest sampling and analysis program in which PrimusLabs personnel collect a representative sample of the commodity from the field and maintain a strict chain of custody from the field to the laboratory for analysis. A product is “Certified” when it meets applicable government standards.

The “Inspected” program is a post-harvest sampling and analysis program in which PrimusLabs personnel collect a representative sample from the loading dock, cooler or distribution center (again utilizing the chain of custody from the sample collection point to the laboratory). Based upon favorable findings, this program can warrant that any pesticide residues detected within the lot analyzed are within established government tolerances.

A “Tested” program is available to any individual or firm concerned with possible pesticide residues that may be present on a specific shipment or commodity. A sample is provided to PrimusLabs by the client, analyzed and the results are then reported to the client.
