Carnival has become the latest cruise ship operator to suspend stops in Mazatlan, citing violent incidents in the Pacific coast resort city.
Carnival Cruise Lines called the decision a precautionary measure, noting that "there have been no incidents involving cruise passengers."
"We are working closely with the Mexican government and local officials to review their plans to improve security in all of the main tourist areas," Carnival said in a statement sent to The Associated Press on Monday. "Once we are comfortable with their plans and implementation, we expect to return to Mazatlan."
The Carnival Splendor and Carnival Spirit ships will replace Mazatlan with additional calls in Cabo San Lucas and Manzanillo, the statement said.
Disney Wonder and Holland America have also recently canceled Mazatlan stops.
Mazatlan is located in the northwestern state of Sinaloa, which is the cradle of several drug cartels and has one of the highest homicide rates in Mexico.
The city has in general been much safer than the rest of the state, with port officials describing crimes against cruise passengers as isolated and minor, such as purse snatchings.
In February, however, two men were shot to death in the parking lot of a hotel frequented by foreign visitors. Neither of the victims were tourists, but guests reported hearing the gunshots.
Last week, five dead bodies were found dangling from bridges over a highway in Mazatlan.
