Our Mission: Reliable Microbiological Food Hygiene Testing

In an industry where a single recall can devastate a reputation, certainty is your most valuable asset. At AGT Labs, we don't just run tests; we provide a comprehensive shield against risk. Our specialized microbiological food hygiene testing services operate under strict ISO/IEC 17025:2017 standards and are FDA LAAF Recognized. From detecting E. coli and Salmonella to routine hygiene monitoring (APC), our facility transforms raw samples into actionable intelligence for your safety program.

Microbiological Food Hygiene Testing Services

Precise microbiological food hygiene testing provides the high-resolution data needed for FSMA compliance and food quality assurance. We utilize AOAC accredited methods for the enumeration of critical indicator organisms and food spoilage analysis including E. coli, Coliforms, and Lactic Acid Bacteria.

Aerobic Plate Count
General Quality & Shelf-Life Predictiony

Aerobic Plate Count

The Aerobic Plate Count (APC) test enumerates mesophilic bacteria that grow in aerobic conditions. As a fundamental component of microbiological food testing, it serves as the primary gauge of total bacterial load. High APC results often indicate temperature abuse in the supply chain or sanitation failures.

Accredited Methods:
  • AOAC 990.12 (Petrifilm™)
  • AOAC 2015.13 (Rapid)
Industry Application:

Used universally across all food sectors (Meat, Dairy, Produce, Prepared Foods) to establish baseline quality specifications and predict remaining shelf-life.

Coliform Testing
Hygiene Indicator & Contamination Check

Coliform Count

Coliforms are a broad group of bacteria found in the environment and the intestines of warm-blooded animals. In our Coliform testing services, detecting these organisms in pasteurized products is a definitive sign of post-processing contamination during food hygiene testing, as they are easily killed by heat.

Accredited Methods:
  • AOAC 991.14 (Petrifilm™)
  • FDA BAM Ch. 29 (MPN)
Industry Application:

Critical for dairy pasteurization verification, water quality testing, and sanitation effectiveness monitoring on food contact surfaces.

E. coli Testing
Fecal Contamination Indicator

E. coli (Generic)

Generic Escherichia coli (E. coli) is a subset of the coliform group exclusively of fecal origin. Unlike general coliforms, E. coli testing provides a direct link to fecal contamination. A positive result raises the probability that pathogens like Salmonella could also be present in the sample.

Accredited Methods:
  • AOAC 991.14 (Petrifilm™)
  • AOAC RI 110402 (Compact Dry)
Industry Application:

Used as a primary safety indicator in fresh produce, raw meats, and irrigation water. It is often a critical control point (CCP) in HACCP plans.

Yeast and Mold
Spoilage Control & Mycotoxin Prevention

Yeast & Mold

Fungi (yeasts and molds) thrive in conditions where bacteria struggle. Beyond visible spoilage, certain molds can produce dangerous mycotoxins. Our microbiological food testing services specifically screen for these organisms to prevent chronic health risks and extend product quality in low-water activity environments.

Accredited Methods:
  • AOAC 997.02 (Petrifilm™)
  • AOAC 2014.05 (Rapid)
Industry Application:

Essential for the bakery industry (shelf-life), dairy (cheese/yogurt spoilage), dried fruits, and acidic sauces. Our rapid methods provide results in 48 hours.

Lactic Acid Bacteria
Anaerobic Spoilage Detection

Lactic Acid Bacteria

Lactic Acid Bacteria (LAB) are facultative anaerobes that ferment carbohydrates. While beneficial in yogurt, they are aggressive spoilage organisms causing fermentation spoilage in meats and dressings. Specialized Lactic Acid Bacteria testing is required to detect anaerobic spoilage issues that standard aerobic counts often miss.

Accredited Methods:
  • AOAC 990.12 (Modified)
  • MRS Broth Enrichment
Industry Application:

Crucial testing for processed meats (hot dogs, deli slices), salad dressings, and shelf-stable acidified products.

Common Questions About Hygiene Testing

What does Aerobic Plate Count (APC) indicate in food testing?
APC measures the total bacterial population in a sample. It serves as a key indicator of overall quality, freshness, and sanitation effectiveness, though it does not identify specific pathogens.
Why are Coliforms and E. coli tested separately?
Coliforms indicate general sanitation hygiene. Generic E. coli is a specific subset of coliforms found in feces; its presence indicates direct contamination and a higher risk of pathogens like Salmonella or E. coli O157.
What are acceptable limits for Yeast and Mold in food?
Limits vary by product type. High counts can cause spoilage, off-flavors, and reduced shelf life. We help interpret results based on industry standards for your specific food category.
Does a low APC result guarantee the food is safe?
No. APC measures general quality. Specific pathogens like Listeria or Salmonella can be present in low numbers even if the total bacterial count is low, requiring specific pathogen testing for safety.
How often should hygiene monitoring be performed?
Testing frequency depends on production volume and risk. We recommend a regular schedule (e.g., per batch or weekly) and increased testing after any process changes or sanitation incidents to ensure consistent control.
What is the turnaround time for standard hygiene tests?
Using rapid Petrifilm™ or Compact Dry methods, we typically provide results for APC, Coliforms, and E. coli within 24-48 hours. Yeast and Mold testing generally requires a 48-72 hour incubation period.
