Pullorum disease is an infectious poultry disease caused by the bacterium Salmonella pullorum. The disease affects mainly young chicks and poults, but can also affect older chickens, game birds, guinea fowl, ostriches, parrots, peafowl, ring doves, sparrows and turkeys.
Fowl typhoid is an infectious poultry disease caused by the bacterium Salmonella gallinarum. The disease affects mainly mature or growing chickens, but has the ability to affect all chickens, ducks, grouse, guinea-fowl, peafowl, pheasants, quail and turkeys.
Both of these diseases are specific to birds and pose a low risk to human health.
However, Health Canada recommends proper handling and cooking of eggs and poultry meat to prevent all potential risks associated with viral or bacterial contaminants.
The clinical signs of pullorum disease and fowl typhoid are very similar. Pullorum disease is generally a disease of young chicks and poults, while fowl typhoid is more predominant in growing and adult birds.
In young birds:
In growing and mature birds:
Canada has been considered free of pullorum disease and fowl typhoid since 1982. There have been isolated occurrences limited to small backyard flocks in Vancouver, B.C.
The most common ways for these diseases to spread is through contact with infected birds, and the transmission from hens to chicks through the egg. Game birds and backyard flocks may act as reservoirs for the infection.
These diseases can also spread via contaminated feed, water and litter, as well as through contaminated clothing, footwear, vehicles and equipment.
Pullorum disease and fowl typhoid may be suspected based on the above clinical signs. Laboratory testing of blood and tissue samples from affected animals is necessary to confirm the diagnosis.
There are no treatments available for these diseases, but the best ways to protect flocks from these diseases are through the following:

Pullorum disease and fowl typhoid are “reportable diseases” under the Health of Animals Act. This means that all suspected cases must be reported to the Canadian Food Inspection Agency (CFIA) for immediate investigation by inspectors.
Canada’s emergency response strategy to an outbreak of pullorum disease and/or fowl typhoid would be to:
In an effort to eradicate pullorum disease and/or fowl typhoid, the CFIA would use its “stamping out” policy, which includes:
Owners whose animals are ordered destroyed may be eligible for compensation.
