Testing for filth & foreign material allows us to measure what is present in the sample which includes but not limited to hair, insects, feces, dirt, contaminants, manufacturing waste, and other by-products.
We screen for filth matter and foreign material in products using UV light and microscopic analyses that isolate and identify potential health hazards. Flotation techniques are also utilized in our testing in order to isolate microscopic filth such as rodent hairs, insect parts, insect eggs, and mites that may contaminate other agricultural crops.
Examination is typically conducted with the naked eye but also may include the use of a hand lens (generally in the range of 3-10X), magnifying ring lamps (3X), or a pair of jeweler's loupes (3-10X). Filth/adulterants in the product are usually not visible to the naked eye and therefore are examined microscopically.
