A Citi Field vendor fatally choked while eating at the Queens stadium following the Mets’ loss to the Phillies Tuesday night, police said.

Hussnain Shah, 30, lost consciousness around 10:30 p.m., according to cops. Stadium workers alerted a police officer, who called EMS and then performed the Heimlich maneuver officials said.

Paramedics gave CPR before taking Shah to New York-Presbyterian Hospital Queens, where he was pronounced dead, police said.

Hussnain lived with his parents in Queens Village and worked full-time at Citi Field, according to neighbor Shahed Islam, 41.

“His younger brother Syed called me last night from the hospital. I couldn’t understand what he was saying he was crying so much,” the neighbor said.

The Shahs came to the US from Pakistan about a decade ago, the neighbor said.

“The family is very loving. Sometimes he’d bring food over to us that his mom had cooked,” Islam said.

The Mets organization referred questions to concessionaire Aramark.

“Words cannot describe how devastated all of us at Aramark, and especially our Aramark colleagues at Citi Field, are by the tragic loss of our co-worker and friend, Hussnain,” said Aramark spokesman David Freireich. “Our prayers and thoughts are with his family and loved ones at this exceptionally difficult time.”

Shah worked at Citi Field for the last two seasons, Freireich said.

The game ended around 10 p.m. with the Mets losing to the Phillies 7-3.
