A trio of cops getting a bad taste in their mouths after downing Shake Shack milkshakes nearly became a flashpoint in the nationwide tensions between police and their communities … but cooler heads are prevailing.

The burger joint was trending overnight because the 3 NYPD officers were hospitalized after complaining about a funny taste in the shakes they ordered at a lower Manhattan Shake Shack. They reportedly described the taste as bleach, and feared they’d been poisoned.

A letter was sent to members of different police unions making them aware of the sitch. In a since-deleted tweet, the NYC Detectives’ Endowment Association straight-up said their boys in blue were “intentionally” poisoned.

The insinuation was cops can’t even go for a shake now without being attacked by rogue citizens. Mind you, there was no evidence of that, but take it as a sign of how tense things are these days.

Welp … an investigation was immediately launched overnight, and NYPD Chief of Detectives Rodney Harrison said Tuesday it was all much ado about nothing.

Harrison says, “After a thorough investigation by the NYPD’s Manhattan South investigators, it has been determined that there was no criminality by Shake Shack’s employees.”

As for what exactly happened to the malts remains a mystery. The NY Post reports it appears to be a cleaning solution commonly used that wasn’t rinsed off the machine enough.

The good news is all 3 cops were released from the hospital and are expected to make a full recovery — and Shake Shack said it’s committed to getting the full picture out.

Crisis averted.
