Descripción
These last years, a fall in consumer's confidence in food safety encouraged
false alerts which sometimes led to actual crisis. This paper studies a crisis due to an alert
concerning a risk of listeria on a raw milk camembert brand. The investigation relies on
individual data. Two results of risk economy are confirmed. Firstly, information has
asymmetric effects, according its positive or negative aspects. Secondly, punctual alerts have
only temporary effects on consumption. In this crisis, education and consumer's habits did not
pay any role.
