The African snail's targets include crops, forests, fruit trees, vegetables, flowers and other plants, and also feeds on paper and companion carcasses when it is hungry, and can even gnaw and digest cement, jeopardizing more than 500 crops. "African snail" is a lot of human and animal parasites and pathogens of the intermediate host, especially the spread of tuberculosis and eosinophilic meningitis, eating is very harmful.

The African giant snail is recognized as one of the worst snails in the tropics and subtropics. It eats large numbers of native plants and changes habitat. Competition for native snails. The African giant snail may also provide an alternative food source for predators, altering the food chain and thus the native ecosystem. If the predator is also an invasive species, there may be unfortunate consequences. For example, invasive cane toads have been found to eat African snails in the Bonin Islands in Japan. However, natural predation may also help control populations of African giant snails. On Christmas Island, for example, African snails have yet to establish in disturbed rainforests; the reason is thought to be that the native Christmas Island red crab eats large numbers of snails.

The African giant snail is a major pest of crops, eating a wide variety of crops and causing serious economic losses.In 1969 the state of Florida in the United States estimated that the African giant snail would cause losses of $11 million per year if populations were not controlled (USDA 1982). In India it reached a state of severe infestation, especially in 1946-47 when it appeared in epidemic proportions in Orissa, causing severe damage to vegetable crops and rice fields. The plants most likely to be damaged by the snail are, garden flowers and ornamentals and vegetables, (especially crucifers, cucurbits and legumes) and young plants of breadfruit, cassava and teak. The African giant snail may also increase the spread of plant diseases (e.g. Phytophthorapalmivora caused by black pod disease) and its spread in its excreta. The African giant snail is a vector for a number of pathogens and parasites that transmit the rodent lung nematode, which infects humans causing a form of meningitis. with the bacterium Aeromonas hyfrophila (Kliks and Palumbo 1992). Parasites in snails are usually transmitted to humans by eating raw or undercooked snails. For example, 16 Korean fishermen in the American Samoa Islands contracted eosinophilic encephalitis after eating a meal of large African snails infected with Angiostrongylus cantonensis parasites (Kliks et al. 1992). (Kliks et al. 1982).

Parasites of the African giant snail include: round nematode of the deep otter cat, round nematode of the Cantonal tube - causes eosinophilic meningoencephalitis, round nematode of the spinal tube - causes gastrointestinal tubular nematode infections, schistosomiasis - the cause of schistosomiasis, which has been detected in feces, whipworms - detected in feces, membranous shell cestodes - detected in feces, and fecal round nematodes - detected in feces and mucus secretion.
