Escherichia coli bacteria in general e. coli is a parcel bacillus known for its abbreviation. Eşerihiya read as a parcel e. coli is a species of bacteria that lives mostly in the large intestine of mammals. Therefore, in environmental waters e. The presence of coli bacteria is a sign of fecal contamination. E. coli bacterium is an organism that has been widely studied in the field of bacterial biology. It would not be wrong to say that escherichia coli is the most common bacterial species among microorganisms.

The excretion of an adult in a day through feces e. The number of bacteria in coli ranges from 100 billion to 10 trillion. The type of bacteria that make up the feces is aerobic bacteria. No effect on animals e. coli bacteria cause diseases when infected. The most well-known of these is O157: H7, causing bloody diarrhea and even death. They can easily multiply from body temperature. E. coli O157: H7 bacteria are the most dangerous foodborne pathogens in the world. In no food product, 25 gram test sample e. coli O157: H7 is not allowed to be found.

Escherichia coli bacteria tests are performed by using special kits. One of them is e. coli O157 bacteria used for rapid analysis and prepared with the principle of immunological flow immunological test kits. Thanks to these kits, after the pre-enrichment stage, 30-40 test results are obtained in minutes.

In advanced laboratories, E. coli counts are analyzed by rapid test methods within the framework of microbiological analyzes. These analyzes are based on domestic and foreign standards and analysis methods. The standard taken into consideration in this regard is:

• TS EN ISO 16654 Microbiology of food and animal feed - horizontal method for detection of Eschericha coli O157
