AOAC Detection of Resistance Genes in Foodborne Microbes
The AOAC International Official Methods for the Detection of Antibiotic Resistance Genes (ARGs) in foodborne microbes is a critical tool in ensuring food safety and public health. This method helps identify potential resistance genes which can lead to antibiotic-resistant bacteria, thus preventing their spread through the food chain.
Foodborne illnesses caused by pathogenic microorganisms resistant to multiple antibiotics are becoming increasingly prevalent due to the overuse of antimicrobial agents in agriculture and medicine. The AOAC International official methods provide a standardized approach for detecting these resistance genes using polymerase chain reaction (PCR) technology, which amplifies specific DNA sequences related to antibiotic resistance.
The procedure involves several key steps including sample collection from various food matrices such as meat products, dairy items, and produce; extraction of microbial DNA; PCR setup with primers targeting known ARGs; amplification process followed by gel electrophoresis or qPCR analysis for quantification. Proper interpretation requires expertise in molecular biology and familiarity with current literature on ARGs.
This service ensures that food producers adhere to regulatory requirements set forth by agencies like FDA, USDA, and EU Commission regarding the presence of antibiotic resistance genes within their products before they reach consumers. By employing this method early in the supply chain, stakeholders can take corrective measures promptly if any contamination is detected.
Our team leverages advanced laboratory facilities equipped with state-of-the-art instrumentation to perform these analyses accurately and efficiently. We ensure strict adherence to international standards including ISO 17025 accreditation which guarantees reliability of results produced by our laboratories.
