Direct detection ofClostridium perfringensenterotoxin in patients' stools during an outbreak of food poisoning

Abstract
An outbreak of diarrhoea in a hotel affected 25 time keepers attending the 1997 Mediterranean Games. Epidemiological investigation implicated a 'pasta al ragù' consumed at the hotel's restaurant and Clostridium perfringens food poisoning was identified by direct detection of C. perfringens enterotoxin in patients' stools. This report confirms that a careful evaluation of epidemiological features, together with the availability of direct and rapid laboratory methods, may lead to a prompt identification of C. perfringens food poisoning.
