Biosecurity is everyday livestock management

PED in swine reminds us that prevention is the best defense against livestock disease

PED virus is a relative of the TGE virus that many of us know from previous years in the pork industry. This PED virus came from the Orient, impacts swine in ways very similar to the old TGE, and began creating havoc and massive losses in the U.S. swine industry last June. To date, through the Jan. 17, the disease has been diagnosed in 2,394 laboratory submissions across the USA and has been confirmed in 23 states.

The top five states in number of positive submissions are Iowa, North Carolina, Oklahoma, Minnesota and Kansas. These five states have 82 percent of the positive case submissions. Missouri is on the list with 18 positive submissions. Some of the studies looking at the spread of this virus have found it present on tires of vehicles, inside cleaned livestock trailers/trucks, and, believe it or not, on the floor of convenience stores frequented by producers and employees.

I won’t spend time on the details of the disease and I don’t want to create a “germophobic” state of mind, but this disease and its devastating effects on infected herds should serve as a reminder to every livestock producer of any species that preventing disease entry into their production operation should be one of the focal points of their management efforts. 

 

Biosecurity is most simply preventing the entry (external biosecurity) and spread (internal biosecurity) of disease in a livestock operation. It requires attention to items coming into the operation (animals, people, equipment, products and services) to make sure they aren’t carrying infectious agents that could be presented to the herd. It also requires attention to how things are done within the operation. It is important to think through exposure points when handling sick animals. Make biosecurity an integral part of logistics as you move feed, equipment and animals from one area of the operation to another. And remember, people moving from place to place should observe biosecurity protocols  to minimize spread of disease if it occurs. We’ve been reminding producers and our own MFA employees that products, people, equipment and animals can play a role in disease spread. 

The early season jackpot and regional shows have begun. As you go to shows, whether you take animals or not, think about biosecurity as you come back home to your own operation. Boots and coveralls can carry disease back home. 

If you take animals to shows, preventing disease may require equipment cleaning and quarantine of show animals returning to the home place. Much the same can be said about visits to livestock auctions and bringing new or replacement animals home.

This discussion is sure to evoke thoughts of extra work and inconvenience. But that is what it takes to do the job right and help prevent disease and the production loss it can create. I read a quote from a veterinarian from Ohio this week that stated, “If biosecurity doesn’t inconvenience you…  you aren’t doing it right.” Doing the extra work and dealing with the inconvenience takes perseverance and encouragement. Be that source of encouragement and remind your customers and coworkers in agriculture about the daily importance of biosecurity.

And the subject could be good discussion and education point for your non-agricultural friends and neighbors!
