In brief: Difficult to say

The best evidence comes from measuring larvae in the organs (liver, brain, eye) of mice after feeding them toxocara eggs.
The liver may be infected as soon as 7 days after ingestion. The brain takes longer & the eyes are the last to be infected. Infection is more likely with frequent ingestion of large amounts of eggs. Many people never get infection after ingestion.Some may become ill years later.
