Microbial Testing for Product Safety and Compliance
Contamination doesn’t just hurt your product. It risks your reputation. At Ayah Labs, we provide fast, precise microbial testing for supplements, skincare, and botanicals, using validated USP and ISO methods to catch issues early, support compliance, and keep your products safe and shelf-ready.
Why Microbial Testing Matters
Microbial contamination can compromise product quality and jeopardize regulatory standing, trigger recalls, and erode consumer trust. That’s why microbiology testing is required by cGMP frameworks, Amazon listing policies, and most national and international health authorities.
For many formulations, especially those with botanical or water-based ingredients, microbial testing is the single most important step before batch release. It confirms the absence of harmful pathogens, identifies spoilage risks, and supports clean-label claims.
Routine testing isn’t just smart, it’s expected. We make it easy to do it right.
What We Test For
Microbial safety isn’t defined by one test as it’s a system of checks that vary by product type, format, and use case. We tailor our testing to meet both regulatory guidelines and the real-world risks of your product category.
Microbial limits for routine quality control
We quantify total aerobic microbial counts (TAMC) and total combined yeasts and molds (TYMC), confirming your product falls within acceptable ranges for release and compliance.
Pathogen detection for regulatory compliance
We screen for objectionable organisms like Salmonella, E. coli, Staphylococcus aureus, and Pseudomonas aeruginosa: microbes known to cause illness and fail regulatory audits.
Yeast and mold monitoring for spoilage risk
Yeast and mold can degrade both safety and shelf life. We help quantify their presence and, when needed, identify species to understand the source of contamination.
Raw material screening for early contamination
Testing ingredients before production protects the entire supply chain. We analyze raw botanicals, powders, and extracts to stop contamination before it enters your batch.
Challenge testing for preservative systems
For water-based or multi-use cosmetic products, we perform preservative efficacy testing (PET) to evaluate how well your formulation resists microbial growth over time.
Facilities and Environmental Monitoring
Contamination isn’t always product-related. It often starts in the environment where products are made. That’s why we offer environmental monitoring services for production facilities, filling lines, cleanrooms, and more.
We sample air, water, equipment surfaces, and production zones to assess hygiene standards and detect contamination trends. Our programs support FDA cGMP compliance and ISO cleanroom standards, helping you build proactive, evidence-backed quality control into your facility operations.
How We Test (and What You Get)
Testing is only useful if the methods are valid and the results are actionable. At Ayah Labs, our microbiological assays follow USP <61> and <62>, AOAC standards, and FDA cGMP expectations, making certain you’re aligned with the guidelines that matter.
USP and AOAC method alignment
All testing adheres to globally recognized microbiology protocols to support quality release, audit readiness, and market entry.
Traditional and rapid microbiology options
We offer culture-based methods for regulatory completeness and faster assays using molecular or ATP-based techniques when turnaround is critical.
Exposure-based risk assessment (when applicable)
For complex formulations, we help interpret microbial findings in context, considering dosage forms, intended use, and shelf life.
Standard turnaround and rush options
Routine results are delivered within 7–10 business days. Need it sooner? We offer expedited service for urgent production or listing needs.
