Three TSA workers at LaGuardia Airport suffered minor injuries this morning. According to PIX 11, "They were harmed when a carry-on bag set off an alarm at a checkpoint at Terminal B, Concourse D."

The FDNY says that it responded to a call at 5:30 a.m. and that the victims complained about irritation to their eyes. The three people were taken to Elmhurst General Hospital. A TSA spokesperson confirmed to Gothamist the injured parties were agents with the administration, and were "[s]ent to hospital for precautionary measures."

The item was described as an "irritating food material" by WABC 7.

Terminal B was closed at 5:49 a.m. "out of caution," a Port Authority spokeswoman said, adding that it was reopened at 6:27 a.m., "Customers should expect delays for checking in."

Update: The Post reports, "The traveler told officials through an interpreter that the substances were merely corn starch, rice flour and potato leaf, police sources said. Officials later confirmed the materials were not hazardous."
