Oftentimes when asking for liver in the market I was told it wasn’t good. Neither butchers nor meat inspectors could provide me with any reasonable explanation. They just wrote it down to parasites.
Since I wasn’t parasite phobic I disregarded theirs warnings and consumed the BAD but discounted livers from time to time. I noticed a pattern that only grass fed and non-dewormed animals (especially sheep) had inferior livers. There always has been a dilemma for me whether to go for CLEAN commercial meat or choose from much better but infected sources.
This issue haunted my mind for quite a while. Finally I cracked this mystery the other day when I was cutting yet another spoiled liver. I found the whole number of Fasciola hepatica in the bile ducts. I surfed the Internet and got all the desired answers.
Here is the most general info on
Fasciolosis.
The Merck Manual also provide some insight on
common liver fluke.
Why animals rarely if ever have liver flukes in the wild?
Control measures for F hepatica ideally should involve removal of flukes in affected animals, reduction of the intermediate host snail population, and
prevention of livestock access to snail-infested pasture. Prevention of livestock access to snail-infested pasture is frequently impractical because of the size of the areas involved and the consequent expense of erecting adequate fencing.How it correlates with my condition?
Chronic or obstructive phase: This phase may develop months or years after initial infection. Adult flukes in the bile ducts cause inflammation and hyperplasia of the epithelium. The resulting cholangitis and
cholecystitis, combined with the large body of the flukes, are sufficient to cause mechanical
obstruction of the biliary duct. In this phase, biliary colic, epigastric pain,
fatty food intolerance, nausea, jaundice, pruritus, right upper-quadrant abdominal tenderness, etc., are clinical manifestations indistinguishable from cholangitis, cholecystitis and cholelithiasis of other origins. Hepatic enlargement may be associated with an enlarged spleen or
ascites. In case of obstruction,
the gall bladder is usually enlarged and edematous
with thickening of the wall. Fibrous adhesions of the gall bladder to adjacent organs are common. Lithiasis of the bile duct or gall bladder is frequent and the stones are usually small and multiple.
So many familiar symptoms… But they are our FRIENDS, the parasites, AREN’T they?
