Eight states (including California, Tennessee, and New Hampshire) have been infected, and eight of them require hospitalization. There are no reports of deaths.
The agency cited patient interviews and laboratory tests, and the results showed that contact with wild songbirds and bird feeders may be the cause of the infection.
The California Department of Fish and Wildlife reported that residents found sick or dead freckles at or around bird feeders, especially in the central coast of the state and the San Francisco Bay area, where they were found to be “submerged.”
In the state, the most common species is the pine tree siskins.
When birds eat bird food contaminated with the feces of other birds, they usually become infected with Salmonella on the ground below the bird feeder.
The agency said that birds usually carry bacteria such as Salmonella, which can spread from birds to pets and then to people.
The CDC says that salmonellosis may cause diarrhea, fever, and stomach cramps in humans. The disease can last for four to seven days, and most people can recover without treatment. However, some serious cases do require hospitalization.
The Centers for Disease Control and Prevention (CDC) recommends that people wash their hands immediately after bathing or touching birds, even if they are in contact with bird feeders, even when wearing gloves. It also recommends cleaning bird feeders outside the house when possible.
