"At this point, we have found no evidence in our own internal investigation, nor have we heard from authorities, that there was any contaminant in the shakes. We continue to await the test results from the NYPD."

The tweet followed the initial update that detailed the company was working to get the facts.

“Our team is working hard to get the full picture. In the meantime, we’re relieved to hear the officers are all okay,” the company tweeted early Tuesday morning.

Shake Shack was responding at the time to a tweet by the NYPD’s chief of detectives, Rodney Harrison, who wrote that investigators had determined “that there was no criminality by Shake Shack’s employees.”

NYPD OFFICERS TAKEN TO HOSPITAL AFTER DRINKING MILKSHAKES AT SHAKE SHACK, 'NO CRIMINALITY'

On Monday night in downtown Manhattan, three NYPD officers went to the hospital after suspecting their Shake Shack milkshakes had been contaminated.

“At some point during their meal period, the MOS [members of service] discovered that a toxic substance, believed to be bleach, had been placed in their beverages,” wrote Patrick Lynch, head of the Patrolmen's Benevolent Association of the City of New York, in a letter to union members. “The contamination was not discovered until the MOS had already ingested a portion of their beverages.”

The officers were expected to survive.

A police source told the New York Post the toxic substance is believed to have come from a cleaning product that wasn't fully removed from the milkshake machine.

So far, no one else has come forward to say they suspected their milkshakes were also contaminated.

Floyd, a 46-year-old black man, died after a white Minneapolis police officer knelt on his neck for more than eight minutes, despite Floyd saying he could not breathe.

“When New York City police officers cannot even take a meal without coming under attack, it is clear that the environment in which we work has deteriorated to a critical level,” Lynch continued in his letter. “We cannot afford to let our guard down for a moment.”

Shake Shack also released a statement soon after the incident happened, writing on Twitter that it was “horrified” to learn of the reports.
