Salmonella vaccines
Salmonella bacteria affect poultry in two ways: host-adapted types cause fowl typhoid and pullorum disease, while Salmonella Enteritidis and Typhimurium often infect birds silently and are a food-safety risk through eggs and meat. Vaccination of layers and breeders, combined with clean feed, rodent control and hygiene, reduces infection and shedding.
Signs to watch for
- Often no visible signs in adult birds (SE/ST)
- Chick mortality, white pasty vents and poor growth
- Diarrhoea, depression and drop in production in outbreaks
Which birds are at risk?
Layers and breeders (food safety and egg transmission); young chicks are most vulnerable to disease.
How vaccination protects your flock
Live and inactivated Salmonella vaccines are used in rearing pullets and breeders according to manufacturer schedules. Vaccination works best alongside rodent control, clean feed and water, and buying chicks from Salmonella-controlled breeders.

Salmonella: common questions
Why vaccinate layers against Salmonella if they look healthy?
Because Salmonella Enteritidis can infect hens without signs and contaminate eggs. Vaccination reduces colonisation and shedding.
How do rodents affect Salmonella?
Rats and mice carry and spread Salmonella; rodent control is essential.
Can Salmonella pass from breeders to chicks?
Yes, some types pass through the egg, which is why breeder flock control matters.
