We provide microbiology lab testing.

Safeguarding food products from microbiological contaminants is critical to food manufacturers. While microbiological analysis ensures your operation is compliant with legislative guidelines, these services also provides assurance of consistent quality and safety for consumers. Our team of expert consultants and scientists work with clients to ensure our food pathogen testing services are comprehensive and meet requirements needed to evaluate products to client and consumer standards.

Microbiological testing in the food industry.

At IEH Laboratories & Consulting Group, we provide analytical services for all major microorganisms, foodborne pathogens, viruses and parasites that could potentially harm food production. Microbial analysis provides a detailed evaluation of your food product and ensures it complies with federal regulations.

Microbiological testing methods.

Microbiological testing labs often times utilize an assortment of testing methodologies to determine the presence of microbes in a given sample. The diverse portfolio of approaches and tools guarentees our laboratories are equipped with the knowledge and resource to meet any analytical need.

Process Control Testing (PCT).

Current tools in microbiological testing are limited to testing for specific pathogens or indicator organisms. The IEH Process Control Testing (PCT) Program takes a wholly new approach, and aims to measure the degree of “control of the production process” based on the simultaneous detection of the presence or absence of multiple broad groups of microbes at various stages of the processes and in the production environment. The broad groups include spoilage organisms, environmental contaminants and groups that share markers with pathogens of interest.

The end result of a PCT test is an index score, the Process Control Index (PCI). The score is generated by a proprietary algorithm. In general, higher scores indicate more biodiversity, and scores which exceed an established threshold are indicative of an increased risk of microbes being present which share genetic markers with pathogens of interest though the target microbes themselves are not pathogens.

The PCI score is suitable for process control for raw material acceptance/qualification programs, finished product quality evaluation and environmental monitoring programs (sanitation efficacy). IEH provides, at no cost, Statistical Process Control (SPC) charts to facilities using the IEH PCT test, similar to the SPC chart shown here.

We provide expedited testing for foodborne pathogens.

Our global network of over 100 laboratories coupled with the knowledge and experience our team of scientists and consultants allows us to fully leverage our analytical services to provide you a service that can quickly isolate and identify microbial contaminants in your facility. Our testing services are made for manufacturers, distributors, retailers, and producers in the food industry. For over 20 years, we've supported thousands of businesses including farmers, packaged food processors, beverage companies, agricultural plants, pet feed producers, and supplement manufacturers.
