LANCASTER, Pa. — Farmers are busy. Stopping to change out of their barn shoes and clothes can be a hassle. But it’s the simplest act that can save their herds from disease.
Penn State Extension veterinarian Hayley Springer laid out the chain of transmission of animal diseases and the steps farmers can take to reduce the risk of an outbreak on their farms during Cattle Feeders Day on Tuesday at the Lancaster Farm and Home Center. Poultry and hog farms generally practice much stricter biosecurity than cattle producers do, but Springer said beef people shouldn’t be scared off. Biosecurity is not all hazmat suits and masks.
“Biosecurity is an everyday thing,” she said. “It’s an important part of every operation.”
There are four different levels of biosecurity plans. Most farmers know of national and regional plans that have been implemented for cases of foot-and-mouth disease and brucellosis. Springer focused on farm-level biosecurity. Beef producers should know the farm’s borders before setting up their biosecurity plan. Farmers will have a better grasp of an outbreak if they can identify boundaries such as a designated parking space for visitor vehicles on their property. What is outside the farm borders, such as another cattle herd, can also be important. For some diseases, cattle on a neighboring farm can pose a transmission risk.
“You can manage what happens inside your farm, but you don’t have a lot of opportunity to manage what happens outside your farm,” she said.
Farm visitors also pose a risk. Many people in the animal ag industry work with livestock on multiple farms. “We want to keep those two herds separate to a point,” Springer said. “We want to respect their herds too.”
Most infections originate from fomite transmission, which is when bacteria or viruses transfer to animals from an object like shoes. Two of the most damaging illnesses in cattle are anaplasmosis and foot-and-mouth disease, and both can spread quickly, Springer said. Foot-and-mouth disease was eradicated in the U.S. in 1929, but a reintroduction could be costly.
The USDA would like beef producers to start using RFID tags. The reason? It will help animal health officials if there’s a statewide disease stop mandate, Springer said.
Producers who practice good animal husbandry are on the right path for biosecurity. Farms should use protocols for vaccines, animal identification and new animals arriving at the farm. Springer suggested farmers practice disinfecting syringes and employ single-use needles when vaccinating their herds. She also reminded farmers that consistent cleaning of equipment is important. New animals should quarantine for 21 to 30 days after their arrival. This allows farmers to do a full health check-up on these cattle and gives an opportunity to a catch disease symptoms early, Springer said.
Cattle with identification like ear tags or RFID tags go with a good biosecurity plan. USDA would like to see more beef producers adopt RFID tags because it will help animal health officials if there’s a statewide disease stop mandate, Springer said.
“If we get a foreign animal disease, we want to know where it is,” she said. “If we can quickly trace back where those animals have been, we can break that down and we can reduce the number of animals under a stop movement.”
Beef producers who practice good animal husbandry are on the right path for biosecurity. Both are something all producers should keep in touch with.
A good plan doesn’t stop at needles and footwear. Beef farmers can encounter risk with contract haulers and their trailers. Swine trailers are disinfected more often than trailers hauling cattle, Springer said.
“When cattle step up on that truck full of manure, they are stepping into that perfect fomite,” she said. “I think whether cattle are coming on or off, we should disinfect those trailers.”
Springer encouraged producers, especially those who contract haulers, to discuss having those trailers cleaned prior to coming on to their farms. Springer used the Beef Quality Assurance Daily Biosecurity Guide, created for producers by the beef checkoff. The guide is also taught in all level one Beef Quality Assurance classes, said Emma Foster, spokeswoman for the Pennsylvania Beef Council.
“It’s something every farmer should keep in touch with,” she said.
