The customer complained of finding a screw in his kebab meal at the eatery in Skane in early March, and the owner of the restaurant -- whose name wasn't released -- told the Dagens Nyheter newspaper the screw was from a pair of tongs used to make salads, The Local.se reported Friday.
The customer complained to the local council's environmental office, which sent out inspectors and discovered the restaurant was using a cement mixer painted blue to make salad dressing and sauces.
The inspectors said pieces of paint were flaking off the machine.
"When I took over the restaurant, the previous owner told me that everything had been approved," the owner told Dagens Nyheter. "When health inspectors pointed out that the cement mixer wasn't acceptable, I threw it out and bought a rust-free mixer the very same day."
