An introduction to food microbiology

Prevalence of food poisoning There has been much concern in recent years over the dramatic increase in food poisoning incidents reported to the government agencies that monitor trends in illness. Analysis of the figures provided by the UK’s Public Health Laboratory Service (PHLS) shows a rise in a number of infections since 1982. The significant increase in food poisoning infections between 1982 and 1990 has been attributed to one type of Salmonella (usually associated with poultry and possibly fresh eggs). Greater public awareness of food poisoning may also be a factor in the continuing increase in the number of cases notified.
