The recall was originally announced Sept. 6 by the Centers for Disease Control and Prevention. It was upgraded Sept. 30 to Class I.

If you have recalled eggs from any of the listed distributors, they should be immediately thrown away. Any surfaces the eggs may have touched should be thoroughly sanitized, including utensils, containers, and your hands. If you suspect you’ve eaten eggs contaminated by salmonella, contact your doctor right away.

The recall, affecting eggs sold in three states, can cause "serious adverse health consequences or death," the FDA says.
