Biosecurity in livestock management

by Tony Martin, DVM

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.

Biosecurity is most simply preventing the entry (external biosecurity) and spread (internal biosecurity) of disease in a livestock operation.

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. .......
