Resumo: | Experimental studies and registries of cases of human toxocariasis have shown that the consumption of raw or undercooked offal of the paratenic host of Toxocara canis may pose a risk of infection. Thus, we evaluated the risk of infection due to the consumption of liver of chickens inoculated with different doses of embryonated T. canis eggs. Doses were 5–100 times smaller than the ones previously employed in this type of study. Groups of five chickens were inoculated with 5000 (control), 1000, 500, 300 or 50 eggs of T. canis, and at 72 h post-inoculation, the liver of each bird was consumed by a BALB/c receptor mouse. Fortyeight hours after consumption, we examined the organs and carcasses ofthe mice for larvae of T. canis. All mice were positive for larvae, except the group that consumed the chicken liver inoculated with 50 eggs. This group contained only one positive mouse, in which the larva was lodged in the brain. In mice that consumed livers of chickens inoculated with ≥300 eggs, larvae concentration was primarily in the liver and lungs, characterizing the initial phase of infection. We conclude that the consumption of raw poultry liver, under the studied conditions, poses a risk of infection even with a low number of infected T. canis eggs. |
