(CNN) -- The U.S. Food and Drug Administration warned consumers on Friday not to eat frozen mamey fruit pulp -- sold under the La Nuestra and Goya brands -- after at least nine people in California and Nevada fell ill with typhoid fever.
Both companies, which have voluntarily recalled the product, get their mamey fruit from a common supplier in Guatemala, the FDA said.
An investigation by the U.S. Centers for Disease Control and Prevention showed a link between an ongoing attack of Salmonella typhi infections and the frozen mamey fruit pulp products. Typhoid fever, which can be fatal, is caused by Salmonella typhi.
Mamey fruit is a sweet fruit with a fleshy orange pulp. It is grown in the tropical lowlands of Central America, the FDA said, and is used to make juices and smoothies.
Officials said both the Goya and La Nuestra products are sold frozen.
