Air Canada is investigating after a passenger found a sewing needle inside a pre-wrapped sandwich on a domestic flight.

The needle was found inside the in-flight meal on a Toronto-bound flight from Victoria on July 30, said the company’s spokesman Peter Fitzpatrick.

“As soon as we were made aware, we immediately contacted the caterers that provision our flights, and a full investigation is under way,” Mr. Fitzpatrick said in an e-mail to the Globe, adding that the airline has not received any other similar complaints. “We are working closely with our caterers to ensure heightened security measures have been put in place.”

He added the airline is co-operating with the police in their investigation.

Earlier this month, the FBI opened an investigation after needles were found inside turkey sandwiches on four Delta Air Lines from the U.S. to the Netherlands. The needles were found inside five sandwiches by the catering company Gate Gourmet, the Associated Press reported. One person was injured.
