Billions of cicadas are emerging in the Eastern U.S. To some, they're a delicacy. To others, they're a danger.
The cicadas are back, and with them a warning from the Food and Drug Administration: Don't eat these critters if you have a seafood allergy.
"Yep! We have to say it! Don't eat #cicadas if you're allergic to seafood as these insects share a family relation to shrimp and lobsters," the agency tweeted Wednesday.
