  • Have strong biosecurity practices in place to protect your farm.
  • Wear dedicated footwear or plastic boots in each individual chicken house to prevent tracking AI inside.
  • Develop and maintain a “line of separation” (clean vs. dirty) at your farm.
  • Change clothes and boots before checking chickens if you have visited any location where other chicken growers may have been.
  • Maintain a good rodent control program on your farm.
  • Use footbaths (i.e., dry bleach) at control room and chicken house entrances.
