Jay-Z club shut down?

Jay-Z is having some business troubles.

The music mogul’s 40/40 Club was shut down for a slew of health-code violations just a day after its celebrity-drenched $10 million relaunch and now it faces a dreaded “C” grade, according to New York Post gossip column Page Six.

Inspectors found perishable food at dangerously warm temperatures inside the walk-in refrigerator and discovered “hot” food left out on the counter on Thursday.

A worker was also seen mixing salsa with his bare hands.

The refrigerator was at a 60 degrees instead of 41 jeopardizing the safety of 50 pounds of raw chicken wings, 5 pounds of raw shrimp and 100 turkey burgers.

Five pounds of cooked mashed potatoes, meanwhile, were left out at a temperature of 89 degrees, while 10 pounds of cooked rice and 50 turkey burgers were kept at 67 degrees.

All the hot foods should be at least 140 degrees.

“If you have a walk-in place with food like this, you put a hell of a lot of people at risk,” a source said.

“A night of dinner and dancing should not include the risk of contracting food-borne illness.”
