Poultry vaccination lead to big drop in UK Salmonella cases

| January 25, 2013

A recently published article by Professor Sarah O’Brien of the University of Liverpool concludes that the falling incidence of non-typhoidal human Salmonella infections in the UK is associated with the poultry vaccination programmes and other measures taken to control the epidemic of egg-related S. Enteritidis PT4, which peaked in 1993.

Professor O’Brien suggests that a combination of measures taken to control the epidemic was responsible for the successful reduction of S. Enteritidis PT4 in breeding and laying flocks. However, the evidence suggests a strong relationship between the vaccination programmes and the corresponding reduction in human disease.

While the evidence suggests that this story is a good example of a successful public health intervention, Professor O’ Brien warns that new Salmonella problems have since emerged and there is no cause for complacency.
