Partnering with microbiologists to diagnose and prevent diseaseTM

Listeria

Listeria was first discovered around 100 years ago.

Historically, it has occasionally been the cause of meningitis and septicemia, especially in newborn babies. This pathogen received little attention, until the discovery that Listeria monocytogenes could be transmitted to contaminate food. Foodborne outbreaks of listeriosis were reported in North America and Europe in the 1980s, and the incidence of the disease rose steadily year-by-year. In the UK, a peak of nearly 300 cases was reached in 1988 and this is thought to have been the result of a single foodborne outbreak associated with pork pâté.
These outbreaks led the World Health Organization to conclude that L. monocytogenes is an environmental contaminant mainly transmitted to humans through food. Although the incidence of listeriosis is at least 100 times lower than those of other foodborne pathogens, such as Campylobacter and Salmonella, the seriousness of the disease, the high mortality rate (up to 40% in some outbreaks) and the fact that it mainly affects vulnerable sections of the population, has focused a great deal of attention on L. monocytogenes. It has now become the target for much of the microbiological testing carried out by the food industry.
