PARASITIC CYSTS AND LESIONS IN ORGANS

 

 

 

Jenny Turton


Parasitic cysts and lesions in organs

Cysts are a stage in the life cycle of a parasite (they look like bubbles or pearls).

Lesions are abnormal changes in animal tissue (meat, organs and other body parts).

They are seen at the time of slaughter of food-producing animals or in affected organs which are being sold

We are concerned about parasitic cysts and lesions because:

Some can cause diseases in people, which means that control of the parasites is important

Affected organs are condemned because of an unattractive appearance and therefore nobody wants to buy them

Some of them can also cause loss of production, disease and even death in livestock
