An outbreak of Salmonella Enteritidis infections, phage type 14b, occurred in the United Kingdom. A total of fourteen outbreak clusters were reported in England and Wales and were linked to a number of catering establishments and a long-term care facility. The clusters may be linked to eggs sourced from outside of the United Kingdom, possibly Spain. Supposedly there was a very low incidence of Salmonella in eggs that originated within the United Kingdom. More than 85% of UK-produced eggs were produced under the British Lion scheme, which required vaccination of hens against Salmonella and other food safety measures.
