A Chinese restaurant was shut down after an investigation found that its ‘roast duck’ was made from dead street pigeons.

There are many daring eaters out there who will try practically anything, even the Swedish delicacy surströmming, which causes many people to vomit.

Occasionally all you need to see is how something is prepared to turn you off for good, and it appears that duck pancake aficionados may be next on the list.

Regulars at a Chinese restaurant in Madrid may never want to eat crispy duck again after discovering what they were actually eating, as part of a frightening police probe that has resulted in the eatery’s closure and the proprietors being investigated.

Police visited the Jin Gu eatery in the Spanish capital’s Usera district late last month and discovered what they deemed to be very unpleasant.

The footage shows dishes full of plucked and fried pigeons. While wood pigeons might be a delicacy in some upper-class restaurants, you don’t want one seized off the street and served directly to your dish.

That is something even raw meat and milk-consuming gym dudes would not contemplate. Maybe.

The footage also shows twisted slices of beef hanging from clothes horses, which is clearly unsanitary.

Local media reportedly stated that unlabeled and undated meat and fish were allegedly kept in non-functioning freezers, while police said there were also cockroaches and rat traps strewn around the kitchen, which may warrant a food hygiene rating negative.

According to investigators, there were no thermometers to assess the temperatures in storage places, which may clearly lead to germs, and the cookware they used was heavily rusty.

Sea cucumbers, which are prohibited by severe maritime rules, were only one of numerous unlawful products discovered inside the restaurant, and the proprietors are now under investigation as authorities seek to prosecute them for public health offenses, animal cruelty, and consumer violations.

Street pigeons can spread diseases, which should be roasted off at the restaurant, but given their cooking issues, I wouldn’t eat that.

Jin Gu now has a 4.2-star Google rating, with several excellent reviews.

“The duck, I think, is a little dry and has lots of bones, not that tasty,” one from five years ago says.
