Hog Farm, Chapter 9: Moms, Farmers Employ Extreme Protocol Against Germs

Moms know a lot about germs or, at least, how they get shared. In mid-winter, we take our kids to the library, grocery store, or museum and usually a few days later said kids have runny noses – or worse. The battle rages on and we keep fighting, armed with our sanitation gear. “Wash your hands,” we dictate, before school, after school, after playing, before eating, after going to the bathroom – wash, wash, wash – “with soap and warm water, please!” Along with the tissues and wet wipes, we carry around two or three mini-bottles of hand-sanitizer in our bags. We use disinfectant wipes on all those nasty surfaces – you know the ones. Our mantra becomes “Cover your mouth when you cough,” “Sneeze into your elbow,” “We don’t share toothbrushes, drinks, or silverware!” We take our shoes off at the door. We keep sick kids home. And, oh, putting everything in their mouth before they turn two – yuck! We can’t see all the germs, but we sure do know they are there. Do some of us go to extremes? We can’t seem to do enough to stave them off, no matter how much "ammunition" we employ.



Farmers do even more than moms to prevent the spread of disease. I was surprised to learn that hog farmers (and other livestock producers, as well) go to extreme measures (by our "mom" standards) in their battle against pathogens. They refer to the germs by more scientific and specific terms like pathogens, micro-organisms, bacteria, or viruses. Their program is far more formal than ours, of course, and theirs has a name. It is called “biosecurity.”

Defined, “biosecurity” is a strict isolation and sanitation program practiced throughout farms to prevent the spread of disease between herds. The livestock farmers we have been talking to take this very, very seriously. In fact, when asked what the ideal hog (livestock) farm would look like, Eldon Gould said, as isolated and remote as possible. All in the name of disease prevention.

I had no idea that pigs, especially young pigs (and all market pigs are young) were so susceptible to diseases, just like our own children. As an example, this past year, and especially this winter, there has been a virus called PEDV (porcine epidemic diarrhea virus) that has proven very difficult to control and has spread rapidly across borders, killing several million piglets. It’s not a new virus, but it is the first time it has been seen in the U.S. You may have seen in the news, there is a possibility that we may see the economic effect of this virus at the supermarket this summer in the form of higher prices for pork. It is just one of many diseases that a young pig can easily contract.

Some farmers in harder hit (by PEDV) locations, like Iowa, have stepped up their strict biosecurity protocols, even going so far as to ask farm-hands to not go into town to avoid contact with other farms (think shoes and tires); and they will avoid parking in parking lots that could fit a large farm truck trailer. It affects everyone’s daily life, on and off the farm.

The two Farm Moms who joined our group for the tour have hog farms of their own. As part of standard biosecurity protocol, they could not set foot in their barns for 72 hours prior to the trip to the Gould Farm. They actually extended it an additional day out of respect for the Goulds. They, in turn, had to wait 72 hours to set foot back in their own barns. They also brought a change of clothes with them to change into after being in the barn, in addition to wearing the protective gear we wore.

Here’s a standard biosecurity protocol that surprised a lot of us Field Moms. At the Gould Farm and Hagenbuch Family Farm (one of our Farm Moms), everyone who goes into the barn must shower in and shower out. You read that right. Hagenbuch’s have two barns and our Farm Mom is in and out of them twice a day – add that up, eight showers in the barn, every day. Yes, it is true! We couldn’t believe it. For our Gould farm tour, we were given a free pass on the showers, but we did have to wear Tyvek® coveralls, hair nets, and giant plastic bag boots over our boots. They went in the dumpster after we came out of the barn. Visitors to the farm are not the norm and biosecurity is the reason why.

Physically, the barns are separated from other parts of the operation like the farm house, field operations, and other barns. Part of a stepped up protocol may also include a series of steps to physically isolate delivery trucks (feed, supplies, fuel, etc.) from the hog housing. The Farm Moms explained a scenario I would not have considered. A truck that has been to an infected farm can pick up the disease on its tires. Then, the snow plow can spread the disease on the roads, taking the pathogens toward the next farms. A dog, or wild animal, walking on the road and back to the farm can bring along those pathogens.

The hog buildings are secure to keep out undesirable animals, both wild and domestic. Cats, dogs, birds, bats, and rodents of all kinds can carry the pathogens on their bodies.

Raccoons and deer used to spread trichinosis when the animals were housed outside. Trichinosis is extremely rare, now, and all but non-existent in supermarket meat. Moving the pigs inside has helped manage those types of risks.

The isolation barn is part of the biosecurity program to protect the herd health. The new-to-the-farm gilts live in the isolation barn, separate from the rest of the herd. Their health is closely monitored for at least two weeks. When deemed healthy, they are moved into the main barn with the rest of the herd. Some farms may also have a hospital barn to treat sick animals and isolate them.

Washing and sanitizing crates after pigs are moved out is standard procedure.
Keeping the animal living quarters clean and sanitary is part of the standard protocol.

Biosecurity focuses on herd health. It’s good for the pigs, good for the farmer, and ultimately, good for us (the consumer) as well. The farmers would much rather keep the pigs healthy than treat sickness.
