Wild birds may carry and transmit diseases to commercial poultry flocks. Certain diseases, such as salmonella and coliforms, may be transmitted from the dam to the offspring through the egg. Poor sanitation also can cause disease problems. Once a site is contaminated, carryover from previously infected flocks may become a reoccurring problem. Disease outbreaks are influenced by the general condition of the flock.
Conditions caused by poor management can reduce the flock's resistance to infection.
Disease prevention Proper security measures can greatly reduce the chance of disease outbreaks. Use disinfectant foot baths or wear plastic foot-coverings when entering buildings. Change foot baths often to keep them effective. If you use equipment for more than one flock, wash and disinfect it before introducing another flock or using it in another building. Only bring in poultry from disease-free flocks.
