ISO 11133 Culture Media Quality Assurance – Latest Updates
ISO 11133 and its latest amendments describes the preparation, production and performance testing of culture media from this whole area. Since its publication as a full ISO standard for food and water microbiology, it has been implemented in many labs, but still there are many open questions for the daily lab work.
Our on-demand webinar gives practical tips for daily handling of culture media including preparation, shelf-life testing, microbiological and physical performance testing amongst other topics
Revised ISO 11133 and ISO 17410 Standards
ISO 11133:2014+Amd1:2018 is a mandatory standard for all ISO 17025-accredited labs for microbiological analysis of food, feed and water. It describes the preparation, production and performance testing of culture media from this whole area. Planned publication of amendment 2:2019 contains the control strains for the performance testing of confirmation and characterization media, reagents, dyes, stains and materials described in standards for the microbiological examination of samples from the food chain and water.
The technically revised edition of ISO 17410 specifies a horizontal method for the enumeration of psychrotrophic microorganisms that are able to grow at 6.5 °C. It replaces ISO 6730:2005 (IDF 101:2005), “Milk — Enumeration of colony forming units of psychrotrophic microorganisms — Colony-count technique at 6.5 °C” and ISO 8552:2004 (IDF 132:2004) “Milk — Estimation of psychrotrophic microorganisms — Colony count technique at 21 °C (Rapid method)”.
We summarized the latest changes in both these standards in a webinar for you.

Spoilage and Sterility Tests in Beverages: New Revised IFU Method No. 12 for Detection of Alicyclobacillus in Fruit Juices, and Sterility Testing of Aseptic Filling Lines
Alicyclobacillus spp. can be difficult to control in fruit juice products as their spores survive juice pasteurization temperatures and may germinate and grow after processing if conditions are suitable. The economic impact of such incidents can be very high. The International Fruit and Vegetable Juice Association (IFU) Microbiological Working Group has revised, improved and validated their worldwide accepted method for the detection of Alicyclobacillus spp. in fruit juices with improved culture media formulations including performance criteria which are in agreement with ISO procedures.
Our on-demand webinar explains the new revised IFU Method No. 12 from 2019 for detection of Alicyclobacillus spp. in fruit juices and provides information about validation of aseptic filling lines in beverage production.
Short Talk: Regulatory Compliance of Culture Media Based Detection of Pathogens Webinar
This 10-minute presentation focuses on ISO regulations for the detection of the most important pathogen, Salmonella spp., in the food chain and describes how the regulatory compliance for the required culture media can be made transparent for laboratories.
Latest Amendments of the ISO 11133:2014 and the Revised ISO 16649 Part 1:2018 for Enumeration of Escherichia Coli in the Food Chain
ISO 11133:2014 is a mandatory standard for all ISO 17025-accredited labs for microbiological analysis of food, feed and water. It describes the preparation, production and performance testing of culture media from this whole area. Recently published amendment 1:2018 contains corrections and additional explanations whilst future amendment 2 will describe the performance testing of confirmation media and reagents.
ISO 16649-1, which specifies a horizontal method for the enumeration of β-glucuronidase-positive Escherichia coli, has also been revised. The method uses a colony-count technique after resuscitation using membranes and incubation at 44 °C on TBX agar. There are three horizontal methods (ISO 16649-1, ISO 16649-2 and ISO 16649-3) for the enumeration of β-glucuronidase-positive Escherichia coli, all parts are for general application. Parts 1 and 3 include a resuscitation step and should be used in preference for foodstuffs likely to contain sub-lethally injured cells.
Watch our on-demand webinar below to learn more about the latest amendments of the ISO 11133:2014 and the revised ISO 16649 part 1:2018.
Revised ISO Food Microbiology Standards for Detection of Listeria, Enterobacteriaceae and Cronobacter
How can you stay ISO certified in the current environment of an ever-increasing, but necessary regulation? In 2017, the food microbiology ISO standards for ISO 11290, ISO 21528, and ISO 22964 were all updated. All food products and ingredients intended for human consumption and the feeding of animals are implicated, along with environmental samples in food production and handling areas. To help guide you through the most recent changes for handling the testing of Listeria (ISO 11290), Enterobacteriaceae (ISO 21528), and Cronobacter (ISO 22964), we have summarized the important points for you in our regulatory news flyers, available for download below. An on-demand webinar from our food microbiology expert—a member of the German ISO delegation—is also available.

ISO 17025 Accreditation and ISO 11133:2014
How does ISO 17025 accreditation for quality control according to ISO 11133 standard lead to a quality increase in water and food microbiology testing? ISO 17025 accreditation specifies the quality management and technical requirements laboratories must meet to demonstrate technical competency and compliance with regulatory standards. The new EN ISO 11133:2014 describes the preparation, production and performance testing of culture media and applies for food, feed and water analysis. ISO 11133 is now mandatory for all accredited microbiology labs. This webinar explains the responsibilities of labs and media suppliers and the benefits of being ISO 17025 accredited for performance testing according ISO 11133.
Salmonella Detection in the Food Chain: Revised EN ISO 6579-1 Promises Greater Flexibility for Testing Labs.
In early 2016, the International Organization for Standardization (ISO) plans to publish the EN ISO 6579-1 standard, which specifies a horizontal method for the detection of Salmonella spp. in the food production chain. Like the preceding version, EN ISO 6579:2002/Amd 1:2007, it will cover products intended for human consumption, animal feeding and environmental samples in food production and handling as well as milk and milk products (previously described in ISO 6785 I IDF 93) and samples from the primary food production stage. It will give greater flexibility for testing labs e.g. for the choice of some culture media and for the range of incubation temperature.
