PSE is caused by a combination of factors which stress the animal and cause a rapid decline in meat ph.

Preventing PSE (Pale Soft Exudative Pork) in Pigs

  1. Provide adequate pen space in holding pens at the plant. All pigs must have room to lie down.

  2. During hot weather wet animals down with sprinklers.

  3. Allow 2 to 4 hours of rest prior to stunning.

  4. Handle and drive animals quietly and reduce or eliminate electric prod usage. Excited pigs are more likely to have poorer quality pork.Pork quality can be ruined during the last five minutes prior to stunning. This is why it is so important to handle pigs quietly.

  5. NEVER fill the forcing pen more than one half to three quarters full. Animals need room to turn so they can enter the race more easily.

  6. Pigs must always have access to water.
