Biosecurity Precautions

When a new animal moves onto a farm, be sure that the health status and the source of the animal is known.
New animals or animals returning to a farm should be separated from the rest of the herd for at least two weeks.
Exclude foreign visitors from farms for at least five days after arrival in the U.S. Ask foreign visitors or people traveling to foreign countries to provide information about recent farm and animal contacts.
Clothing worn on farms in other countries should be washed and footwear should be disinfected; luggage, camera and other items should be cleaned and disinfected.
All footwear should be disinfected before entering and after leaving an animal housing area.
Discourage walking through feed mangers.
Keep vehicles, such as milk, feed and livestock trucks, from driving through areas where animals are housed or feed is kept.
