The NYPD cop who bit into a glass-packed Big Mac is suing McDonald's and the culprit who booby-trapped the burger for $6 million. Veteran cop John Florio swallowed at least five razor-sharp shards when he chomped into the tainted burger on Jan. 30.

The K-9 unit cop had stopped at the McDonald's at 875 Garrison Ave. in the Bronx for a dinner break.

Burger-flipper Albert Garcia Jr., 18, later confessed he had brought a broken picture frame from home, ground up the glass and sprinkled it on the Big Mac.

"Both this restaurant and the McDonald's corporation failed to properly supervise the employee," said Florio's lawyer, Richard Kenny, who planned to file the lawsuit today in Bronx Supreme Court.
