Meanwhile, another New York City police officer has been disciplined for action against demonstrators during protests over the death of Floyd.
On Monday evening, three officers went to the restaurant in Lower Manhattan, but as they ate their meals, they began to feel sick while drinking the milkshakes.
The Legal Aid Society, a public defender organization that has pushed for police reforms, said the move was "welcome news", but cautioned that New Yorkers would not be better served "if these officers are simply reassigned, carrying with them the same bad habits that earned Anti-Crime its dismal reputation".
"Our team is working hard to get the full picture", Shake Shack tweeted Tuesday morning.
A police officer was suspended without pay for macing a group of bystanders during ongoing protests in the city, NYPD Commissioner Dermot Shea said Monday.
