An infected dog or a cat will have eggs of this parasite in its feces and if for any reason an individual comes in contact with contaminated feces either through swallowing soil or by any other means then he or she will get infected with Toxocariasis. In some extremely rare cases, some people have been infected with Toxocariasis by eating undercooked meat which contained eggs of the parasite.
