The safety of pasteurised in-pack chilled meat products with respect to the foodborne botulism hazard

There has been a substantial increase in sales of pasteurised in-pack chilled products over the last decade. It is anticipated that this trend will continue. These foods address consumer demand in being of high quality and requiring little preparation time. The microbiological safety of these foods commonly depends on a combination of a minimal heat treatment, refrigerated storage and a restricted shelf-life. The principal microbiological safety hazard for pasteurised in-pack meat products is foodborne botulism, as presented by non-proteolytic Clostridium botulinum. This review provides a summary of research that has contributed to the safe development of these foods without incidence of botulism.
