The ISO 16654 standard, developed by the International Standards Organization (ISO), describes a horizontal method for the detection of escherichia coli serogroup O157. Subject to the limitations discussed in the introduction to this standard, this standard applies to products intended for human consumption or animal feed.
For the purposes of this standard, the expression escherichia coli O157 refers to microorganisms that form typical colonies on the surface of the coating medium used in this standard and produce indole and agglutinate, especially with antiserum against the O157 antigen.
Since food and feed products are very diverse, this horizontal method is not suitable for some products in every detail. In this case, different methods specific to these products are used if absolutely necessary for justified technical reasons. However, every attempt should be made to apply this horizontal method as much as possible.
If there are international standards or national standards that are not compatible with this horizontal method for certain product groups, when such standards are reviewed, they are modified to comply with the ISO 16654 standard. Thus, in the end, the only remaining deviations from this horizontal method are those necessary for well-known technical reasons.
Escherichia coli O157 causes serious life-threatening diseases and has a low infection dose. Laboratory-acquired infections are common.
Escherichia coli (or e. coli for short) is one of many bacterial groups that live in the intestines of healthy humans and the warmest-blooded animals. E. coli bacteria help maintain the balance of the normal intestinal flora against harmful bacteria and synthesize or produce some vitamins. However, hundreds of e. coli bacteria type or strain. Among them, E. coli known as O157 e. coli strain causes a serious intestinal infection in humans andIt is the most common type to cause disease.
Within the scope of ISO 16654 standard, our organization, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, Microbiology of food and animal feeds, also provides testing services in accordance with the horizontal method for the detection of escherichia coli O157.
