- Parasites become important if they occlude the pancreatic duct directly or induce inflammation
- Commonly caused by flukes of families Opisthorchidae and Dicrocoelidae when present in large numbers and overspill from the billiary tract
- Nematodes, particularly ascarids, and cestodes occasionally lodge within pancreatic ducts
- In pigs, Stephanurus dentatus can form cysts in the pancreas after migration through the liver
- Parasites tend to cause chronic interstitial pancreatitis
- Tend to destroy acinar tissue, islets of Langerhans being unaffected
