U.S. egg farmers are committed to providing consumers the safest and highest-quality eggs, and it is a top priority for farms to implement biosecurity and health protocols to help protect their hens from disease. Egg farmers work closely with animal health experts and veterinarians to monitor their flocks and keep them as healthy as possible.

While every egg farm is different, a number of rigorous biosecurity measures are being used on farms to prevent disease. Examples are shown in these photos.

Many egg farms house their hens indoors to prevent exposure to wild birds, waterfowl, pests and rodents that may spread disease. For the same reason, farms also limit movement of personnel, vehicles or equipment between farm operations.

Egg farms only allow essential employees and service providers onto the farm, to limit the opportunity for disease to be accidentally carried onto the farm by vehicles or on visitors’ clothing or footwear.

Upon entry on the farm or into a barn, approved vehicles, footwear and equipment are disinfected using one of several methods.
