​Testing for Porcine Reproductive and Respiratory Syndrome (PRRS) and Porcine Epidemic Diarrhea Virus (PEDv) is not required for swine to go to the market for slaughter sales (where all swine on the premises the day of the sale move from the market directly to slaughter).  To avoid the need for testing, these animals must arrive at and leave the market on the day of the sale.  Slaughter swine from herds that have tested negative within 90 days prior to import may arrive at the market prior to the slaughter sale day if they meet regular import requirements for movement to non-slaughter sales, including a CVI.  Additionally, other swine that may arrive at the market for other sale days may not arrive at the market until all slaughter swine have left the premises.

Swine imported to federally approved markets and then going directly to slaughter are not required to have official individual ID, testing, a CVI, or an import permit, but federal rules require the following:

• Paperwork, such as a yarding receipt, sale ticket, waybill, bill of lading or bill of sale, that includes all of the following:   
  

• Location, including street address, from which the animals originated

• Animal identification numbers when required.
  

• ONE of the following types of identification is required:

• Official Identification
  

• USDA ear tag number – number must begin with a state 2-digit code followed by 2 or 3 letters and 4 numbers

• USDA "840" ear tag number

• Ear notch (if the pig is a purebred and the ear notch is registered)

• A tattoo or an ear tag with the premises identification number and a unique identifier (a tag without the premises ID number is not sufficient)

• ​Breed association tattoo 

• Feeder swine:

• If the animals are 80 pounds or less, individual ID is not required but the premises identification number or state-issued code of the premises of origin must be on the animals (ear tag or tattoo).
  

• If the animals are more than 80 pounds, each animal must have official individual ID as noted above.
  

• Slaughter Identification

• Official Backtags

• PIN (Premises Identification Number) tags

  ** Please note: many slaughter establ​ishments are requiring the PIN tags.
  

• Tattoos consisting of the PIN number or feeder swine number assigned by the state veterinarian of the state of origin.
