Re-emerging zoonosis are zoonotic infections that have been recognized before and has protocol measures of prevention and treatment in place,but now these infections have higher incidences and wider geographic scope. Fascioliasis is one of such re-emerging zoonotic infections that was common in developing nations of Africa and sparse dispersion in America,Europe and Asia. Today this infection is widespread and with higher prevalence. The food-borne trematodes causing infection in man are Fasciola hepatica and gigantica are the 2 most common in the tropics. Transmission is by ingestion of flukes in under-cooked or poorly processed liver. Drinking water contaminated with the flukes and eating water plants or vegetables washed with such water. Accidental ingestion of flukes from infected liver as shown below is very common in developing countries. Butchers usually cut up affected liver in strips to cut out the white tracts formed by the flukes. This is usually called Eedo oni ishan, they typically sell to food vendors and people who want meat that you chew for long before swallowing. The next time you visit your butcher and observe livers cut up with tracts,donot buy.
