Eating unwashed fruit or vegetables that were grown in contaminated soil can also cause ascariasis. Although the infection can occur in any part of the world, it is more common in developing countries with poor sanitation and areas where human feces are used as fertilizer.
Intestinal parasites are primarily transmitted by fecal-oral route, mostly via ingestion with contaminated food and water or during direct hand to mouth contact. Food items which are usually consumed raw, like fruits and vegetables, are potential sources of infection.
Small children often play in dirt, and infection can occur if they put their dirty fingers in their mouths. Unwashed fruits or vegetables grown in contaminated soil also can transmit the ascariasis eggs.
Unwashed fruits and vegetables also can carry tapeworm eggs. Lack of sanitation and sewage. Lack of sanitation and sewage for human waste increases the risk of livestock getting tapeworm eggs from people. This increases the risk of people eating infected meat.
Consuming raw and improperly washed vegetables is a major way in which human pathogens are transmitted [10, 11]. Because of poor hygienic practices related to planting, harvesting, packing, transportation, and storage, fruits and vegetables can become easily contaminated with parasites [11].

At hatching, tomato fruitworm larvae are creamy white caterpillars with a black head and conspicuous black tubercles and hairs. Larger larvae vary in color from yellowish green to nearly black and develop fine white lines along the body but retain the black spots at the base of bristlelike hairs.
A wide range of parasites can potentially be transmitted via contaminated fresh produce, including berries, and some have been implicated in outbreaks of disease. Three protozoan parasites, Cyclospora cayetanensis, Cryptosporidium parvum, and Giardia duodenalis, were considered in the present study.
Vegetables, fresh fruit and mushrooms represent a potential source of infection by a variety of pathogens including the tapeworms, Echinococcus granulosus and E. multilocularis. The sexually reproducing forms of both of these worms use various canines as their hosts.
A person with intestinal worms may not have any symptoms, but threadworms (Enterobius vermicularis), the most common worm infection in Australia, often do cause symptoms. A person with threadworms (also known as pinworms) may have an itchy bottom or redness and scratch marks around the bottom.
