dc.description.abstractTrichinellosis is a parasitic zoonotic disease caused by a nematode of the genus Trichinella. It is cosmopolitan and affects most mammals, birds and reptiles. It is spread by eating raw, undercooked meat or meat products containing the trichinae worm. In this study, trichinellosis in patients attending three hospitals in Kaduna metropolis, Nigeria and slaughtered pigs at pig abattoir in Angwan Television, Kaduna South Local Government Area, Kaduna was detected. Risk factors associated with Trichinella infection were also determined using close-ended structured questionnaire administered to the patients. A total of 472 serum samples were processed and tested serologically for antibodies to Trichinella by ELISA using excretory-secretory (E/S) antigen. There was an overall human prevalence of 16.13% while Prevalence of 13.4% was observed in the pigs studied. Out of the 186 pig serum samples collected, 56 were from juvenile pigs while 130 were obtained from adult pigs. Adult pigs recorded a higher prevalence of 14.6% than the juvenile pigs, 10.7%. Male pigs had a prevalence rate of 12.6% which was slightly lower than that of the female (14.1%). The survey also revealed that out of 100 pig farmers and owners 90% had scavenging pigs, 98% had seen rodents around and within their piggeries, 85% had no rodent control programme, 70% feed their pigs with food leftovers, 4% had seen their pigs interact with stray pigs, 16% feed their pigs with dead animals and 10% had seen snakes around their piggeries. Only 2% of the respondents were aware of trichinellosis while 30% knew of pork-borne diseases. Significant association existed between all the risk factors in the backyard pig farms visited at p≤ 0.001 with trichinellosis except for seeing of rodents around and within pig pens. There was no significant association in the demography of the human population studied. However, male participants had 16.1% prevalence while female participants recorded 16.5%. Respondents within the age range 40-49 years had the highest prevalence of 21.2%. Association of risk factors with trichinellosis was assessed and the type of meat eaten was significantly associated (χ2 = 19.192 p=0.002) with trichinellosis with beef eaters, having the highest prevalence of 29.5%, pork eaters 11.4%, poultry eaters 8.0%. Eating of hamburger/sausages revealed a significant association (χ2=4.091, p=0.043). Respondents knowledge of how Trichinella infects pigs was significantly associated with trichinellosis (χ2 = 6.348, p=0.042). The survey for farm management practices associated with trichinellosis was carried out using close-ended structured questionnaire administered to 100 pig farmers. The result showed the distribution of pig owners based on farm management practices as extensive system (55%), semi-intensive (40%) and 5% intensive system; Prevalence rates of 96.4%, 70.0% and 0.0% respectively were recorded and showed a significant association at p≤0.001 (χ2=32.89, p<0.001).The study has established a serological evidence of trichinellosis in humans and slaughtered pigs in Kaduna metropolis, Nigeria. ELISA test was recommended to be included in the routine tests in hospitals and in slaughterhouses for quick detection of trichinellosis.en_US
