Microbiology Testing for Supplements, Cosmetics & Foods

Accurate microbiological testing to ensure product safety, regulatory compliance, and shelf stability.

Microbiology testing laboratory at Qalitex

Microbiology testing detects and quantifies microorganisms — including bacteria, yeast, mold, and pathogens — in consumer products to verify safety, support shelf-life claims, and meet regulatory requirements such as USP <61>/<62> and FDA 21 CFR Part 111.

Qalitex Laboratories specializes in microbiological testing services designed to verify product safety, extend shelf life, and support regulatory compliance. Our testing protocols follow USP <61> and <62>, AOAC guidelines, and FDA regulations, ensuring your products meet the strictest standards for microbial safety.

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.

Pathogen Screening

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.

Yeast and Mold Testing

We perform enumeration and speciation testing according to USP and AOAC methods to identify and quantify yeast and mold contamination in supplements, dried foods, and cosmetics.

Raw Material Microbial Testing

We provide tailored microbial analysis to screen for pathogens and total microbial loads in raw botanical powders, extracts, and other ingredients before production, helping ensure supply chain integrity.

Environmental Monitoring

We provide environmental monitoring programs to assess manufacturing facility hygiene and contamination risks, testing surfaces, air, and water to ensure compliance with FDA cGMP and ISO cleanroom standards.
