Supermarket loyalty cards helped to pin down an outbreak of Salmonella in sausage in France last year.
Researchers reported in Eurosurveillance last week that an outbreak of the monophasic variant of Salmonella enterica serotype 4,[5],12:i:- occurred in November and December 2011 in France. Epidemiological investigation and food investigation with the help of supermarket loyalty cards suggested dried pork sausage from one producer as the most likely source of the outbreak. Despite the absence of positive food samples, control measures including withdrawal and recall were implemented.
