According to reports, this snail is called the African large snail, also known as the brown cloud agate snail.
In the 1930s, it was introduced as food to Fujian and Taiwan in China for breeding, and as a result, because of its rapid reproduction and rapid spread in nature, it became one of the first 16 invasive alien species in China, and was also listed as a class II quarantine pest in China.
Experiments have found that the mucus or feces of this African giant snail carry many parasites and pathogenic bacteria, especially Guangzhou tube roundworm.
Guangzhou tube roundworm mainly parasitizes mice, and the intermediate hosts include African large snails, Chinese round field snails, Dongfeng snails and so on.
If it enters the human body through the skin and mouth, it will parasitize in the central nervous system or cerebrospinal fluid of the human body, causing meningeal and encephalitis, meningitis and myelitis, and the condition can be fatal or disabled.

African large snail invasion
Cases abound
1
Florida, USA
On April 15, 2013, Taiwan's Daily News Cloud reported that thousands of rat-like "African giant snails" invaded in Florida, USA. The invasion of African giant snails in Florida began in 1966, when a child brought three snails from Hawaii back to Miami, and within 7 years, they had become a huge population of 17,000. The local government spends millions of dollars a year on snails, but after each rainy season, they grow explosively. A single female snail can lay 1200 eggs a year and eat lime like crazy to replenish calcium and promote the development of the shell. In addition, they transmit murine lung nematode, which has the potential to infect humans and cause a type of meningitis.
2 Nanning, Guangxi
On September 20, 2013, african large snails appeared on the outskirts of Nanning, which are extremely fertile. This "pastoral killer", which was listed as one of the first 16 invasive alien species in China, is extremely harmful to crops such as vegetables and is a class II quarantine pest for The entry and exit of china. The African giant snail is a plant-eating xerophytic snail with strong reproductive ability, and its diet involves hundreds of herbs, woody and vines, which are extremely harmful to flower beds and farmland crops, and are known as "pastoral killers". Although the African giant snail reproduces extremely quickly, it has natural enemies in Guangxi and can be killed with pesticides, so it has not caused a large-scale outbreak.
3 Fuzhou, Fujian
In July 2014, Ms. Cao, a resident of Fuzhou, China, saw a "giant snail" near Tongpan Road. Experts have identified this as the "African giant snail", one of the first harmful invasive alien species announced in China, and in the 1980s, many people in Fujian had farmed it, but after being banned, farmers threw them into the wild. This snail can spread tuberculosis and eosinophilic meningitis, so it cannot be touched by hand, let alone eaten. It has long been banned by China, and this time it was found in Rongcheng District, suspected to be secretly cultivated.
