A family party near Fresno, California, resulted in 10 people being treated for botulism, a rare but serious illness caused by bacteria that affects the nervous system, public officials said Friday.
The culprit in the outbreak? Home-canned nopales, or cactus pads.
Two sisters are currently recovering in intensive care, a spokesperson for the Fresno County Department of Public Health told NBC News. One sister underwent a tracheostomy, a procedure to create a breathing tube in the neck, due to respiratory complications caused by the disease.
The eight other hospitalized individuals have been released, and there have been no new reported cases since.
