  • As visitors to arrive on farm with clean close and footwear, or provide disposable footwear.
  • Accompany visitors on the tour.
  • Minimize the amount of contact between visitors and animals.
  • As visitors leave, instruct them to wash hands and boots with detergent.

  • Follow the same measures for low and moderate-risk individuals.
  • Visitors should arrive with clean coveralls, boots and equipment.
  • Trucks and livestock trailers should be clean before arrival on the operation.
