We understand from the Food Standards Agency, which has responsibility for food borne disease, that the causes of individual (sporadic) cases of salmonella rarely provide sufficient evidence of their cause to enable an epidemiological investigation to be undertaken to identify their cause. For this reason individual cases are not routinely investigated or traced to identify the food responsible.

In order to demonstrate that cases of laboratory confirmed Salmonella infection are due to eating United Kingdom produced chicken or duck eggs it is necessary to conduct epidemiological and/or microbiological investigations which can provide the required scientific evidence of association. This is only usually possible for cases linked to recognised outbreaks of infection, which involve two or more cases affecting individuals from more than one household.

The following tables show the number of laboratory confirmed cases of salmonellosis as part of reported outbreaks of infection between 2007 and 2012 where investigations showed that infection was transmitted through the consumption of contaminated chicken or duck eggs produced in the UK.
