More than 70 people across seven states have been sickened due to a salmonella outbreak linked to eggs recalled by a California-based egg distributor, according to the US Centers for Disease Control and Prevention.

The outbreak has been tied to multiple brown organic and brown cage-free egg brands distributed to grocery stores in seven states, officials said.

Egg Company recalled about 1.7 million brown organic and brown cage-free egg varieties distributed to grocery stores between February and May.
