Shake Shack, a popular burger chain in and around New York City since it debuted 10 years ago, has been accused of being the culprit of food poisoning for Phillies manager Ryne Sandberg and Mets first baseman Lucas Duda at its Citi Field location, according to ESPNNewYork.com's Danny Knobler.

The restaurant, which is located just beyond the center field fence, served burgers to Sandberg and Duda over the teams' weekend set in New York.

"A couple of coaches took a bite and didn't like what they saw and threw the rest away," Sandberg said to reporters before the Phillies' game against the Angels on Tuesday, adding that he lost six pounds in two days after eating the burger. "I was in a rush so I ended up putting it away.

"I had one piece of toast in two days, and I'm feeling fine about that. I don't want anything in my stomach."

Duda said before the Mets' game at Yankee Stadium on Tuesday that his burger was undercooked. He was hospitalized on Friday afternoon but has played every game since then.

"The first we heard of this situation was about an hour ago via Twitter," Greg Waters, senior manager for marketing and communications with Shake Shack said on Tuesday evening. "We're attempting to get in touch with Ryne Sandberg to learn more. At this point we have no further knowledge of the situation, and there have been no other related reports whatsoever. Food safety is of paramount importance to us, and we're connecting with our management team at the Citi Field Shake Shack now to discuss further and find out more."

The Mets are also investigating the matter, a team official said on Tuesday.
