After hauling a load of market hogs, it's essential that you properly clean and disinfect your trailer. If you hire a trucker, make sure he's doing the same.

Here are a few tips from a National Pork Board and American Association of Swine Veterinarians' swine health fact sheet written by veterinarian Robert Thompson.

1. Scrape bedding and large debris out of the trailer before entering the wash area. If you didn't use bedding, soak the trailer before washing it to reduce wash time.

2. Using soap will help loosen debris and reduce wash time. It's best to apply soap and water on low pressure to the outside of the truck or trailer first.

Move inside to the front of the top deck and start the soap application at the junction of the floor and side. Work up the sides from bottom to top. This reduces streaking and gives more surface contact time.

Next, soak the roof and floor while working to the back of the trailer. Soaking the whole trailer will give plenty of time to loosen debris. However, don't allow the soap to dry or it will be harder to rinse.

3. After you apply soap to the entire trailer, move back outside and start rinsing and cleaning the trailer from the top down. After rinsing the trailer, soap and wash the cab to provide additional soaking time inside the trailer.

4. Rinse and clean each deck from front to back and the ceiling down, starting with the top deck. Always remember to spray the flooring support members on the ceiling of the bottom deck in a multiple-deck trailer, behind all the gates, in all the corners and the inside of the roll-up door. Also wash unloading ramps.

During the winter it is essential to wash all the winter panels as well as the storage box after every trip. Through- out the year, be sure to wash and disinfect sorting boards, paddles, boots and coveralls after
every load.

5. The trailer is rinsed inside and out, apply the disinfectant at the appropriate dilution rate. Start on the inside of the trailer and finish on the outside. A disinfectant should be applied at low pressure because many of the metering devices will not dilute properly on high pressure.

6. Clean out the inside of the cab, wash and disinfect the floor mats.

7. After disinfecting, park the truck on a slope so all the remaining water can drain out. During the winter, leave the truck in the washout bay or park it in a protected area to prevent it from freezing up.
