===Transmission===
Transmission of ''Toxocara'' to humans is usually through ingestion of infective eggs.<ref name="CDC3"/><ref name="CDC1">{{cite web | publisher = Centers for Disease Control and Prevention.| work = Division of Parasitic diseases. | title = Guidelines for Veterinarians: Prevention of Zoonotic Transmission of Ascarids and Hookworms of Dogs and Cats. | date = 27 September 2004 | url = https://www.cdc.gov/ncidod/dpd/parasites/ascaris/prevention.htm |access-date=2017-09-17 |url-status=live |archive-url=https://web.archive.org/web/20100821105900/http://www.cdc.gov/NCIDOD/DPD/PARASITES/ascaris/prevention.htm |archive-date=2010-08-21 }}</ref> ''T. canis'' can lay around 200,000 eggs per day.<ref name="Cheprasov"/>  These eggs are passed in cat or dog feces, but the defecation habits of dogs cause ''T. canis'' transmission to be more common than that of ''T. cati''.<ref name="Markell_2006"/><ref name="CDC1"/> Both ''Toxocara canis'' and ''Toxocara cati'' eggs require a several week incubation period in moist, humid, weather, outside a host before becoming infective, so fresh eggs cannot cause toxocariasis.<ref name="Markell_2006"/><ref name="Huh, Sun, Sooung"/><ref name="CDC1"/><ref name="Cheprasov"/>

Many objects and surfaces can become contaminated with infectious ''Toxocara'' eggs.  Flies that feed on feces can spread ''Toxocara'' eggs to surfaces or foods.<ref name="Holland_2006"/> Young children who put contaminated objects in their mouths or eat dirt ([[Pica (disorder)|pica]]) are at risk of developing symptoms.<ref name="Markell_2006"/><ref name="Despommier"/><ref name="Holland_2006"/> Humans can also contaminate foods by not washing their hands before eating.<ref name="Huh, Sun, Sooung"/><ref name="CDC3"/>
