A Facebook user has sparked alarm online after sharing photos of sushi purchased from a well-known restaurant glowing an eerie blue in the dark.
The discovery left the customer too frightened to eat the food, prompting a scientific explanation from experts who warn that “glowing food” can be a real but dangerous phenomenon.
The user, posting under the name Mind Burusskorn, on Sunday shared images of the suspicious sushi along with a caption describing the experience:
“I bought sushi from a well-known brand. As I got out of the car and turned off the lights, I noticed a blue glow coming from one piece. It was only that single sushi — the one I’d asked the staff to make fresh because the tray had run out. I was so shocked I didn’t dare eat it. I’ve never seen anything like this before.”
Following the viral post, food scientists confirmed that glowing food is indeed possible through natural chemical reactions — but it often signals bacterial contamination. Certain species of bacteria can produce light when seafood or fish begins to spoil due to improper storage conditions.
The glow, visible in darkness, is a warning sign. Experts say consumers should never eat food that appears fluorescent, as it may pose serious health risks.
