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 pathogens like Listeria and Salmonella to routine hygiene monitoring (APC), our facility delivers precise data 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 including E. coli, Coliforms, and Lactic Acid Bacteria.

Aerobic Plate Count analysis for microbiological food hygiene testing
General Quality & Shelf-Life Prediction

Aerobic Plate Count

The Aerobic Plate Count (APC) test enumerates mesophilic bacteria that grow in aerobic conditions. As a fundamental component of microbiological food hygiene 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)
Technical Specs:

Sample Size: 100g minimum | LOD: < 10 CFU/g | Shipping: Refrigerated (2-8°C)

Industry Application:

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

Coliform detection in microbiological food hygiene testing
Hygiene Indicator & Contamination Check

Coliform Count

Coliforms are a broad group of bacteria found in the environment. Detecting these organisms in pasteurized products is a definitive sign of post-processing contamination detected during microbiological food hygiene testing, as they are easily killed by heat.

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

Sample Size: 100g or 1 Environmental Swab | LOD: < 10 CFU/g | Shipping: Refrigerated

Industry Application:

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

E. coli screening for microbiological food hygiene 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)
Technical Specs:

Sample Size: 100g or 1 Environmental Swab | LOD: < 10 CFU/g | Shipping: Refrigerated

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 microbiological food hygiene testing
Spoilage Control & Mycotoxin Prevention

Yeast & Mold

Fungi (yeasts and molds) thrive where bacteria struggle. Our microbiological food hygiene testing services specifically screen for these organisms to prevent chronic health risks from mycotoxins and extend product quality in low-water activity environments.

Accredited Methods:
  • AOAC 997.02 (Petrifilm™)
  • AOAC 2014.05 (Rapid)
Technical Specs:

Sample Size: 100g | LOD: < 10 CFU/g | Shipping: Ambient or Refrigerated (Do not freeze)

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 analysis for microbiological food hygiene testing
Anaerobic Spoilage Detection

Lactic Acid Bacteria

Lactic Acid Bacteria (LAB) can be beneficial or destructive. Specialized microbiological food hygiene testing is required to detect these facultative anaerobes in processed meats and dressings, where they often cause fermentation spoilage that standard aerobic counts miss.

Accredited Methods:
  • AOAC 990.12 (Modified)
  • MRS Broth Enrichment
Technical Specs:

Sample Size: 100g | LOD: < 10 CFU/g | Shipping: Refrigerated (2-8°C)

Industry Application:

Crucial testing for processed meats (hot dogs, deli slices), salad dressings, and shelf-stable acidified products. Control these organisms by monitoring food quality parameters like pH.

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.
