The UK’s Animal and Plant Health Agency (APHA) reported 6% more isolations of Salmonella in animal feed in 2020.

The agency said 756 isolations of the bacteria were found in compound animal feedstuff and feed ingredients. A total of 107 isolations of Salmonella serovars were found in feed, which was up nearly 22% from 2019 and 70% from 2018. An isolation is a report of a single culture of Salmonella from a group of livestock.

A total of 38 isolations of S Typhimurium were identified, followed by 29 isolations of S Infantis and 28 isolations of monophasic variants of S Typhimurium. The most common serovars included S Tennessee, S Rissen and S Kedougou.

The APHA found 273 isolations from pet food meant for raw consumption – up around 11% from 2019 and 45% from 2018. Among pet food, S Indiana was the most common serovar, followed by Derby and Mbandaka.

Among livestock, APHA detected more isolations of Salmonella among pigs (up 13.2%) and chickens (a 27% increase) compared with 2019 numbers. Isolations were lower among cattle, sheep, turkeys, ducks and geese, and game birds. The agency found no isolations at all among deer and rabbits, and 41 from horses, just around a third of 2019 data.
