A rapid isolation method for E. coli Type I is being presented: A 4-6 hours resuscitation period at 24 +/- 3 degrees C is immediately followed by the 44 +/- 0.1 degrees C incubation period. Using this method the result can be read off after 24 hours, in exceptional cases after 48 hours. This technique enables the demonstration of an hygienic parameter important for food microbiology within a short time. Examinations will now be started in the Federal Health Office with the aim for defining E. coli-standards for various foods. It is planed to recommend these standards to the federal health authorities for including them in appropriate food regulations.
