ISO 21528-2 Enterobacteriaceae Enumeration in Dairy Products

The enumeration of Enterobacteriaceae is a critical aspect of ensuring food safety and quality, particularly for dairy products. The ISO 21528-2 standard provides a standardized method for the recovery, isolation, and counting of Enterobacteriaceae in liquid and solid dairy samples. This service is essential for companies looking to comply with international standards, ensure product quality, and protect consumer health.

The Enterobacteriaceae family includes a variety of bacteria that are naturally present in the gastrointestinal tracts of humans and animals. In food products, some species can cause spoilage or pose a risk to human health if not properly controlled. Therefore, accurate enumeration is crucial for maintaining product integrity and safety.

The ISO 21528-2 method involves several steps: sample collection, preparation, inoculation of selective media, incubation, and counting. The process ensures that all Enterobacteriaceae are recovered from the samples without interference from other microorganisms. This is achieved through the use of specific growth media and incubation conditions tailored to favor the recovery of these bacteria.

The standard specifies the use of m-Endo agar for liquid dairy products, while a combination of m-Endo agar and MacConkey agar may be used for solid dairy samples. These media are designed to selectively recover Enterobacteriaceae from complex matrices like milk or cheese without inhibiting their growth.

The enumeration process is performed in two steps: the first step involves incubation at 30°C for 18 hours, followed by a second incubation at 42°C for up to 168 hours. This allows Enterobacteriaceae to grow and form visible colonies on the agar plates that can be counted manually or with an automated colony counter.

The standard also provides guidelines for sample preparation, including homogenization of solid samples and dilution of liquid samples. Proper sample handling is crucial to ensure accurate enumeration results. The service offered by Eurolab ensures that all steps are performed in strict accordance with the ISO 21528-2 protocol.

The results from this test provide valuable information on the level of Enterobacteriaceae present in dairy products, which can be used to monitor production processes and ensure compliance with food safety regulations. This is particularly important for companies that produce high-risk foods like dairy products, where even small contamination levels could lead to serious health issues.

The ISO 21528-2 method is widely recognized as a robust and reliable technique for enumerating Enterobacteriaceae. Its use ensures consistency across different laboratories and helps to establish a global standard for the testing of dairy products. This, in turn, contributes to higher standards of food safety and quality.

In conclusion, the ISO 21528-2 method is an essential tool for ensuring the safety and quality of dairy products. By providing accurate enumeration of Enterobacteriaceae, this service helps companies meet regulatory requirements, protect consumer health, and maintain a positive brand reputation.
