US federal health authorities have reported a salmonella outbreak that has infected dozens of people across seven western and midwestern states.

The outbreak is linked to organic brown eggs and non-caged brown eggs distributed between February and May by the August Egg Company, which has since recalled the affected products due to potential contamination.

According to the Centers for Disease Control and Prevention (CDC), 79 cases of salmonella infection have been confirmed across the states of Arizona, California, Illinois, Indiana, Nebraska, New Mexico, Nevada, Washington, and Wyoming. Twenty-one individuals have been hospitalised.
