Philadelphia Phillies Manager Ryne Sandberg and New York Mets first baseman Lucas Duda each claim that undercooked burgers from Shake Shack gave them food poisoning during the teams’ series over the weekend.

On Tuesday, Sandberg told reporters that he lost 6 pounds in two days after eating a funny-tasting Shake Shack burger from the restaurant’s branch at Citi Field. “A couple of coaches took a bite and didn’t like what they saw and threw the rest away,” he said, according to ESPN. “I was in a rush so I ended up putting it away.”

Shortly thereafter, Sandberg fell ill, and was unable to eat anything but toast for two days. “I had one piece of toast in two days, and I’m feeling fine about that. I don’t want anything in my stomach, he said.

Duda’s bout with food poisoning resulted in his hospitalization on Friday. The 28-year-old confirmed that he had eaten an undercooked Shake Shack burger, but a Mets spokesperson said that the food was cooked at a different branch. Duda was unable to play in Friday’s Mets-Phillies game.

Greg Waters, senior manager for marketing and communications for Shake Shack, addressed the food-poisoning incident in a statement on Tuesday.

“We’ve served thousands of guests at our Citi Field over the past week, and this is the first we’ve heard of any issue whatsoever,” the statement said. “We take every guest concern of any sort seriously, and as such reached out to Ryne Sandberg to get more information since we have not heard from him. We stand by our food quality 100%.”
