Parasites of cattle and swine slaughtered in selected abattoirs in Cotabato Province, Philippines
2018
Besana, C.M.
Samples were collected from four randomly selected abattoirs in Cotabato Province [Philippines]. Abattoir characteristics, operations, and practices were also observed and recorded in the study. Blood, fecal, and organ samples were collected from 35 slaughtered swine and 15 slaughtered cattle. In swine, fecal examination showed an overall parasite prevalence of 60% in observed fecal samples belonging to subclass coccidia (42.86%), Trichuris suis (8.57%), hookworm/strongylid and Strongyloides sp. (5.7%) and Ascaris suum (2.85%). In cattle, fecalysis showed 53.3% prevalence for parasite eggs belonging to Fasciola sp. (33.3%), amphistome and hookworm/strongylid (13.3%), and Capillaria sp. (6.67%). Adult parasites observed in slaughtered cattle were Fasciola sp. (33.3%), amphistomes (26.67%), and Setaria sp. (6.7%). ELISA tests showed that all swine samples were seronegative for cysticercosis while 31.43% were seropositive for Toxoplasma. Results of Person's correlation and logistic regression analyses showed that variables including sampling sites (municipality and wearing of uniforms of slaughter personnel in selected abattoirs were not good predictors for parasite occurrence. Finally, animal rearing practices play an important role in transmission of diseases and parasites in livestock. Environmental contamination of parasite eggs/oocyst should also be taken into account as their infective stages may persist in the environment for a long period of time, increase the chances of infecting and re-infecting animals, and also has implications to public health. Furthermore, improvement of diagnostic techniques for detection of livestock diseases must be done in order to prevent its transmission to other animals, or to humans.
