MANAGEMENT, CONTROL AND REGULATIONS
During the last two decades, VTEC O157:H7 has risen in importance as a public-health risk worldwide. It is considered that up to one- third of domestic ruminants are healthy, subclinical carriers of O157:H7 and are the main reservoirs for human infections.
Diagnostic methods have been developed to selectively detect O157:H7 in human clinical cases and food. For the latter, a validated International Standard detection method (EN ISO 16654:2001) is available. According to the World Organisation for Animal Health (OIE), emphasis should be given to the isolation and identification of E. coli 0157 and other VTEC from carrier animals(22). On a mandatory basis, EU member states annually report their data on detection of VTEC/STEC in food and animals to the European Commission and the European Food Safety Authority based on Directive 2003/99/EC. In Germany, Verocytotoxigenic E. coli- associated disease in domestic animals must be reported to the appropriate federal state authority. Currently there is no comprehensive surveillance for E. coli and E. albertii in wild animals, or recommendations for E.coli control in these species.
