    when they enter interstate commerce, which may or may not include an interstate
  • Interstate commerce means the swine are sold, transported, received for transportation, or
    offered for sale or transportation between parties in different states. .

PIN Tags
Beginning Jan. 1, 2015, many major U.S. pork packers and processors began requiring a USDA-approved, official premises identification number (PIN) swine tag on all breeding swine they purchase.

PIN tags are applied to breeding stock prior to going to slaughter as a means to do a post-slaughter trace. Tags are considered official ID, and must not be removed at any point in the life of the animal. Application of the PIN tags is the responsibility of the producer. The number on the tag coincides with the premises ID number of the farm the sow or boar was on prior to harvest. In Indiana, the premID number is issued by the Indiana State Board of Animal Health.   

Packers/processors that have announced a PIN tag requirement in all breeding swine include: Johnsonville, Hillshire Brands, Calihan Pork Processors, Bob Evans Farms, Wampler's Farm Sausage, Pine Ridge Farms, Pioneer Packing Co., Pork King Packing, and Abbyland Pork Pack.
