Research – Salmonella in animals and feed in Great Britain2022

Gov UK

This publication presents data on Salmonella reports from livestock species in Great
Britain (England, Wales and Scotland) collected and collated by the Animal and Plant
Health Agency (APHA) during 2022 and also provides data from previous years for
comparative purposes.
The data in the first 12 chapters cover reports of Salmonella in livestock, with separate
chapters for the main species, reports of Salmonella in dogs, reports of Salmonella in
wildlife and reports of Salmonella in animal feedingstuffs. The 13th chapter covers the
antimicrobial susceptibility of Salmonella (England and Wales only).
Since 1993, the date of a Salmonella incident has been recorded as the date it was
reported to an Officer of the Minister. Under the present system, any Salmonella reports
that are confirmed or identified after the publication of the annual report will be
incorporated into the revised tables that appear in the following year’s publication. This
may result in the number of incidents and isolations differing from that previously given for
a particular year. The most recent version of the report should therefore always be used
when comparing data from year to year.
Revisions in the way that data have been compiled and presented since 1993 mean that,
with the exception of the tables on Salmonella in animal feedingstuffs, data in this report
cannot be compared directly with information published prior to 1993. A more detailed
comparison can be generated, if required, for any Salmonella serovar, or phage type in the
case of S. Enteritidis and S. Typhimurium. Requests for such data should be made to the
Department of Epidemiological Sciences, APHA Weybridge (email address:
Foodbornezoonoses@apha.gov.uk), who will be happy to assist with requests.
Care should be taken when comparing data from one year to another as an increase or
decrease in the number of isolations and incidents does not necessarily indicate a similar
change in prevalence. This is because the total number of samples examined and their
distribution are often not known.
