When 34-year-old engineer Mark Wilson from Manchester came home from work one evening, he decided to have a simple dinner — nothing fancy: bread, potatoes, and pickles. He took a new jar from the shelf, bought earlier that day at a local supermarket. It was a well-known brand, the packaging airtight, the expiration date fine.
Mark set the jar on the table, grabbed the opener, and with a soft pop removed the lid. Instantly, the familiar smell of brine and dill filled the air. But when he looked inside, he froze. Among the pickles, half-hidden by the cloudy brine, was a dark green shape. At first he thought it was just a badly peeled cucumber. But then he realized — it wasn’t a vegetable.
Carefully, he tilted the jar so the liquid drained, and to his horror a frog floated to the surface — intact, its limbs stretched, eyes closed. For a moment, Mark couldn’t believe what he was seeing. He set the jar on the table and stepped back, a chill running down his skin.
The first thing he did was grab his phone and take a picture. Then he called the supermarket’s customer service line. The woman on the other end thought it was a prank — until he sent her the photo.

“Please don’t touch the jar,” she said after a pause. “We’ll send someone over to inspect it.”
Two hours later, a store manager arrived with a health inspector. They examined the jar, took photos, and wrote a report. The verdict shocked everyone: the jar had been sealed at the factory, not tampered with. The frog had been pickled together with the cucumbers — its tissues soaked in brine, the packaging perfectly airtight.
Experts later suggested the animal had accidentally ended up among the fresh cucumbers during loading at the plant, unnoticed by the automated line. The company asked Mark to keep quiet, offering compensation and replacement products, but he refused. He posted the story and photo online — and it spread instantly across British news outlets.
A few days later, the manufacturer issued an official statement, promising an internal investigation and stricter sanitary controls. Still, social media users wrote that after this story, they’d never look at pickles the same way again.
As for Mark, he says he now eats only homemade preserves — and every time he opens a jar, he first checks who might be inside.
