Summary

Verotoxin (VT)-producing Escherichia coli O157:H7 was culturable on agar media after being left in water for 21 months. However, there were a number of colonies which had lost O157 O antigenicity. These colonies produced VTs, which are pathogenic to humans. These observations suggest that the immunologic method based on O157 O antigenicity are unable to detect and isolate VT-producing E. coli in foods and other environments if the organism has been under starvation conditions for a long period.
