Microbial Limit Testing
Our comprehensive microbial limit tests detect and quantify total aerobic microbial counts (TAMC), total yeast and mold counts (TYMC), and specific objectionable organisms including E. coli, Salmonella, Staphylococcus aureus, and Pseudomonas aeruginosa.

Our pathogen screening covers Salmonella, Listeria monocytogenes, E. coli O157:H7, Clostridium, and other pathogens relevant to your product type. Early detection prevents product recalls and protects consumers.
Preservative Efficacy Testing (Challenge Testing)
Preservative efficacy testing (PET), also known as challenge testing, assesses how well a product's preservative system inhibits microbial growth over time. Vital for products with water content or susceptible to contamination during use. We follow USP <51>, ISO 11930, and industry best practices.
