The studied results showed that the infection rate of pigs with Cysticercus cellulosae larvae in Bac Yen, Muong La and Mai Son districts was 3.13%, 2.67% and 1.99%, respectively. The average number of larvae in a pig was from 1 to 9 (in the muscle), from 1 to 7 (in the brain), from 1 to 4 (in the kidney), from 1 to 3 (in the heart). The infection rate of pig increased by age. The infection rate of pig in the summer-autumn season was higher than in the winter-spring season. The infection rate of the local pig breeds was higher than that of the hybrid pig breeds. The infection rate of the free grazing pigs was 4.91%, of the half grazing pigs was 1.32% and of the completely confined pigs was 0.65%. In high mountain area, the infection rate of pig was 3.89%, in the low hill area, the infection rate of pig was 2.33%, and in plain areas, this rate was 0.94%. The free grazing and semi-grazing pigs facing with the risk of Cysticercus cellulosae larvae infection was 2.04 - 7.58 times higher compared to the captive breeding pigs.
