Farm Biosecurity Procedures for Dairy Inspectors

There are many variables in keeping biosecurity measures in place when inspecting a dairy facility. Dairy inspectors need to use good judgment and practices to avoid contamination from farm to farm.

  1. The dairy inspector will follow any reasonable biosecurity procedures the producer requests.
  2. The inspector will always park the car in as clean an area as possible.
  3. The dairy inspector will use one of the two (A or B) following procedures to keep footwear as clean and sanitary as possible.
  4. Wear disposable plastic foot-coverings over rubber boots. **
  5. Put on the disposable coverings before leaving the car.
  6. Complete the inspection. Wash any manure off of the plastic boots in the parlor or milkhouse with a water hose. This helps to prevent tracking of manure out to the car.
  7. Remove disposable coverings just outside of the car. Remove coverings by grasping the top and turning the boot inside out while removing them. If it is not possible to leave them on the farm, place used coverings in a plastic enclosable bag and/or Rubbermaid container that has a tight-fitting cover.
  8. If disposable coverings get torn, boots are to be washed and sanitized.


    1. Wash boots thoroughly and then use an effective sanitizer. Boots need to be made of smooth rubber and cover the ankle and worn on the outside of the pant leg.
    2. Effectively sanitize boots before or upon entering the milkroom. Follow all label instructions on the sanitizer container.
    3. Complete the inspection.
    4. Wash boots to remove all manure with a water hose in the parlor or milkhouse. This helps to prevent tracking the manure out to the car.
    5. Effectively sanitize whole area of boots before re-entering car. This can be done with: Brush and bucket, stepping into bucket/pan, or spraying clean boots.
  1. Inspectors need to have sanitizer in the car with them. (Don't depend on the producer to have effective sanitizer.) Even if using disposable boots, a method of sanitizing when necessary must be available.
  2. Sanitizers - examples of names and brands that could be used: Grid 10, Chlorine, Lysol, Iodine, Chlorohexidine, Nolvasan, Quats, Laro, Enveron, Cres-400,Tek-Trol, Discan, Synphenol-3
  3. If clothing is significantly soiled, the inspector needs to change clothes.
  4. Inspectors will try to not walk in front of cows, manger area, or feed rooms during an inspection, if possible.
  5. If the inspector is told of, or suspects a herd has an infectious disease, he/she will take all the precautions necessary to avoid contaminating other herds. The farm could be the last stop of the day, or at the inspector's discretion, he/she could avoid entering the barn or animal area for that inspection only.

Other items of concern:

  1. If a producer refuses to allow dairy inspector onto farm because of biosecurity reasons:
  2. Producer's Grade A permit will be suspended immediately (PMO Section 3. Permits: Interference and refusal of inspection pages 5 & 6).
  3. If producer is refusing inspection to prevent disease from entering the farm, producer may sell milk only as manufacturing grade (Grade B) temporary permit for up to 30 days. At that time the inspector must be able to inspect the facility or the permit to sell milk will be revoked.
  4. If producer is refusing inspection because of a disease on the farm, the permit to sell milk will be immediately suspended until it is proven that the disease is not a public health threat and the bulk truck and bulk hauler cannot carry the disease to another farm. When it is determined that there is no public health threat, a temporary manufacturing grade permit will be issued for 30 days. After 30 days, the inspector must be able to inspect the facility or the permit to sell milk will be revoked.
  5. The dairy farm truck approach, hose-port slab, and walkway to the milkroom from the bulk truck must be maintained as clean and dry as possible. This is to help prevent the bulk truck, milk hose, and driver from accumulating manure and feedstuffs, and possibly carrying diseases from one farm to another. Depending on farm management practices, manure, old feed & hay, and pooled water can accumulate in front of the milkroom. This item is a violation on Grade A under Section 19r: Surroundings, but it is only a 1-point debit at this time. Dairy inspectors need to stress this item on inspections and use the authority to order a correction to this problem as soon as possible on both Grade A and Manufacturing Grade farms.
  6. To reach the milkroom on some dairy farms, the bulk hauler has to walk through the dairy barn. This practice can cause the hauler to carry diseases to the next dairy facility. To correct this problem, the dairy producer should provide a clean footbath for the hauler to use as he exits the barn to leave the premises.
  7. ** Plastic boot coverings may not be practical in all situations:
  8. Coverings may not be large enough to effectively cover inspector's feet or may not slip over the feet due to rubberized soles.
  9. In very muddy areas, plastic boots may tend to slip off, even with bands around the top.
  10. Coverings may be slippery in some areas.
  11. Coverings may become punctured under certain conditions.
