African giant snail presence triggers health warnings in Paraguay

Health experts are warning of the presence of the African giant snail in Capiibary, San Pedro, following a massive population increase linked to recent heavy rains. While veterinarian Griselda Meza from the University of Asuncion (Cemit – UNA) clarified that the snail is not poisonous, she emphasized that it can transmit dangerous diseases, including parasites that cause meningitis.

Although initial laboratory samples analyzed by Cemit have not yet detected specific meningitis-causing parasites, Meza has coordinated with the Ministry of Health to alert local medical professionals to monitor for parasitic meningitis in patients. The species is recognized as a significant sanitary problem across the Caribbean and parts of South America, including Brazil.

To manage the snails safely, experts recommend wearing gloves and using sea salt rather than common salt, as the latter can cause stress that increases mucus production and the potential spread of pathogens. For disposal, it is advised to bury the snails using a double layer of plastic and lime to prevent health risks from scavengers like rodents. Additionally, the Ministry of Health advises washing all food with potable water and avoiding direct contact with snail mucus, particularly near the eyes, nose, and mouth.
