China
China is a big consumer of rat meat. It is commonly sold raw in Chinese meat markets, and can also be purchased cooked from various shops and street vendors. Some of the markets in China also offer live rats for sale. Buyers can then have the vendor kill and prepare the rat for cooking, or they can take their dinner home while it’s still alive.
Rat meat is offered for sale alongside many other kinds of animals in China’s meat markets. Bats are common, as are snakes, but interested buyers can find almost any kind of meat they want if they go to the right place. Exotic markets carry many kinds of meats you would never find at a shop in the United States.
Rat is prepared in various ways in China. This is partly a matter of personal taste and partly a matter of how many people it must feed. Grilled or barbecued rat is common and is a favorite with many. The rat will be gutted and skinned and then cooked over an open fire, usually with some type of sauce or seasonings applied. Cooked rat is frequently spitted on a long bamboo spear and sold by street vendors for people to eat as they walk.
Some people in China prefer to eat baby rat meat, and they will even eat them alive after dipping them into a sauce to add a favorite flavor. While this practice is not common throughout the Chinese population, it is done by some. Often restaurants specialize in this dish, as they will have rat pups on hand for just this purpose. Chinese meat markets don’t usually have pups on hand, so people wanting to indulge in this kind of a meal have to go elsewhere for their food. This is not advised as the risks of raw meat consumption, especially in rats, could be teeming with bacterial and viral threats.
Another way that the Chinese eat these animals is by cooking them in a stew. There they may be added to other types of meat and vegetables. Everything is cooked until it is tender and then eaten along with the gravy created by cooking.
