• Microbiology
PCAS
performs a full range of analyses including routine enumeration
of microorganisms, detection of pathogens and toxins. The Microbiology
Department uses accepted methodologies such as AOAC, AHPA, FDA,
USDA, USP and customer-specified tests.
PCAS
helps companies to be in compliance by designing suitable HACCP
plans, monitoring incoming ingredients, environmental cleanliness
and finished product quality. Our Ph.D. graduate microbiologists
are A2LA members and recognized AOAC expert reviewers of new
testing methods. A list of typical testing and projects follows.
