Salmonella control becomes robust only when sampling works as a chain

The UK Animal and Plant Health Agency stresses that Salmonella control in poultry is an operational chain rather than an isolated laboratory test. National Control Programmes cover laying hens, breeding flocks and broilers. They combine biosecurity, regular sampling under defined procedures, testing in approved laboratories, official visits and action when regulated strains are found.

Correct sampling deserves particular attention. A sample does not merely determine the status of one flock; it feeds the surveillance system used to assess sector-wide risk. APHA says official staff verify compliance and biosecurity as well as sampling technique. Traceability of a result therefore starts at collection, not on the laboratory report.

UK figures illustrate the preventive logic. According to APHA’s 2025 annual report, the share of flocks positive for regulated Salmonella was 0.43% in laying hens and 0.004% in broilers. The agency also states that the rise in human cases in England has not, to date, been linked to UK poultry or eggs. That distinction prevents hasty conclusions, but it does not lessen the need for surveillance.
