ATLANTA (AP) _ An estimated 93,000 people get salmonella poisoning every year from handling reptiles, the Centers for Disease Control and Prevention reported Wednesday.

The CDC urged pet stores to do a better job of warning customers that iguanas, snakes and other cold-blooded critters can spread the bacteria to humans through their feces. Most cases could be avoided if people would wash their hands after handling reptiles and keep reptile pets caged, the agency said.

Salmonella can cause diarrhea, fever and nausea and lead to more serious complications in infants and people with weak immune systems.

The CDC estimates there are 1.4 million cases each year of salmonella poisoning from various sources.

Kansas and Maryland have laws requiring pet store owners to give out information with the sale of any reptile. California, Connecticut and Michigan require it only for the sale of turtles.
