PEABODY, Mass. — A woman who just flew back home from Las Vegas says an airport security officer confiscated her frosted cupcake because he thought the icing on it could be a security risk.

Rebecca Hains said the Transportation Security Administration agent at McCarran International Airport took her cupcake Wednesday, telling her its frosting was enough like a gel to violate TSA restrictions on allowing liquids and gels onto flights to prevent them from being used as explosives.

“I just thought this was terrible logic,” Hains said Friday.

Hains, who lives in Peabody, just north of Boston, said the agent didn’t seem concerned that the cupcake could actually be explosive, just that it fit some bureaucratic definition about what was prohibited. She said he even offered to let her eat it away from the airport security area.

Hains, a 35-year-old communications professor at Salem State University, said she told the agent she had passed through security at Boston’s Logan International Airport earlier in the week with two cupcakes packaged in jars, gifts from a student. But she said the agent told her that just meant TSA in Boston didn’t do its job.
