On January 29, 2019, the Animal and Plant Health Inspection Service (APHIS) removed the giant African snail (GAS) regulated areas in Zone T, Zone H, Zone C, and Zone M from the list of quarantined areas in Miami-Dade County, Florida. APHIS and the Florida Department of Agriculture and Consumer Services (FDACS) collaborated to develop the protocol for removing areas from quarantine. Under the protocol, FDACS and APHIS use the following criteria to deregulate a quarantined area/zone:

  • Surveillance and treatment efforts for 17 months with no detection of live GAS

  • An additional 19 months of surveillance with no detection of live GAS

  • A minimum of one negative detector dog survey

  • A minimum of one negative night survey, when snails can be more active

APHIS determined the aforementioned areas met the protocol for removal from quarantine. APHIS and FDACS will continue to evaluate GAS-infested areas to determine when they meet the criteria for eradication and deregulation. The revised map and descriptions of the areas regulated for GAS are posted on the APHIS website at:

Under IPPC standards, Lissachatina fulica is considered to be a pest that is transient, actionable, and under eradication in the United States.
