What is the primary method of preventing salmonella infection in the UK?

The primary method of preventing salmonella infection in the UK is through the vaccination of chickens. By vaccinating chickens against salmonella, the likelihood of the bacteria being present in eggs and poultry is significantly reduced. This approach is effective in minimizing the transmission of the bacteria to humans, as contaminated poultry products can be a major source of salmonella infections.

In the UK, the vaccination programs for laying hens and broilers are part of a broader public health strategy to control salmonella outbreaks. When chickens are vaccinated, they are less likely to carry the bacteria and thus help to ensure the safety of food products derived from them, like eggs and meat.

While boiling foods and the use of antibiotics are relevant to food safety, they do not address the root cause of salmonella infections in poultry as effectively as vaccination does. Avoiding all meat products may reduce exposure, but it is not a practical or necessary approach for many individuals, since properly cooked and handled meat products can safely be consumed without risk of infection.
