Dr Flake is certainly correct that cysticercosis occurs when ova of T solium are ingested from Contaminated sources, or by internal autoinfection.1 Ingestion of raw or undercooked pork that contains Cysticercus larvae is the source of infection for development of the mature worm. However, in endemic areas or where inadequately cooked pork is ingested, chances for acquiring cysticercosis are probably much higher because of a higher prevalence of the mature worm in the population. This was the implication of our statement.
