Food Safety Screening
Microbiological and Chemical Testing for Food and Beverage Safety
Phase 4 Services offers independent testing of food products to detect contamination, verify product safety, and support regulatory compliance. Our lab serves food producers and regulators in Massachusetts, New York, Maine, and nationwide.
We specialize in identifying microbial hazards, chemical residues, and unknown substances using validated methods and defensible reporting.
What We Test For
Microbial Contamination
We perform total plate counts, Most Probable Number testing, and pathogen identification for common foodborne bacteria such as Salmonella, Listeria, and E. coli. Our microbial testing helps determine if a product is safe for consumption or requires recall or reformulation.
Chemical and Toxin Detection
We screen for heavy metals, toxins, pesticides, and residues that may originate from ingredients, processing equipment, or packaging. We investigate off-odors and discoloration to determine the source of contamination or degradation.
Regulatory and Compliance Testing
We assist food manufacturers and distributors in meeting FDA and GMP requirements for food safety and hazard control. Our results support batch release, safety audits, supplier qualification, and investigations triggered by consumer complaints.
