Poultry vaccination reduces salmonella cases in humans, study finds
January 17, 2013
Research has suggested the vaccination of poultry has driven down salmonella cases in humans
A programme that led to the vaccination of poultry against salmonella has driven down the number of cases of the illness in humans.
That is according to research from the University of Liverpool, which explained that salmonella cases soared 170 per cent in the UK between 1981 and 1991.
A voluntary vaccination scheme was launched across breeding flocks of poultry in 1994 and in laying flocks in1998.
Professor of Epidemiology and Zoonoses Sarah O'Brien said that between 1993 and 1996, there were 1.6 cases of salmonella per 1,000 person.
However, this fell to 0.2 cases per 1,000 person when the same study was conducted from 2008 to 2009.
Professor O'Brien commented: "It is probable that no single measure contributed to the decline in salmonella cases but the relationship between vaccination programmes and the reduction in human disease is compelling."
Symptoms of salmonella poisoning include diarrhoea, headaches, nausea and vomiting, fever and headaches, with medical attention recommended in a number of instances such as dehydration and signs of jaundice.
