ISO 16649-1 E. coli Enumeration Testing
The ISO 16649 series of standards is designed to provide a harmonized approach to food microbiology testing, ensuring consistency and reliability in the enumeration and identification of microorganisms within food products. Among these, ISO 16649-1 E. coli Enumeration focuses specifically on the quantitative analysis of Escherichia coli (E. coli) bacteria in various foods.
E. coli is a common indicator of fecal contamination and can be found in many food products if they have been exposed to contaminated water or soil during production, processing, or handling. This test plays a crucial role in ensuring the safety and quality of food products by quantifying potential pathogens that may pose health risks.
The process involves several steps: first, a suitable enrichment broth is used to enhance the growth of E. coli in the sample. Following incubation at specified temperatures (typically 36°C ± 1°C), colonies are counted on MacConkey Agar plates. This method allows for accurate enumeration based on colony-forming units (CFUs).
The test protocol meticulously outlines all necessary steps, from sampling to final reporting, ensuring that results are consistent and reproducible across laboratories. Compliance with these standards is essential for meeting regulatory requirements set by health authorities worldwide.
Our laboratory adheres strictly to the procedures specified in ISO 16649-1, guaranteeing accurate counts of E. coli in your samples. By choosing our service, you can rest assured that you receive reliable data that meets international standards and helps maintain consumer trust.
