animals, including seal meat, whale meat, reindeer meat, and polar bear meat. Brætter do not sell live animals, but most meat sold in brætter is fresh and recently butchered. While larger towns have purpose-built facilities, the brætter in smaller towns and village settlements sell seafood in open-air stands without running water or electricity. Only fresh meat was allowed to be sold in Nuuk at Kalaaliaraq Market, the largest fresh food market in Greenland, until 2018 when the government of Greenland began permitting the sale of dried and salted meat at Kalaaliaraq. Trichinosis is a common problem in Greenland due to the consumption of wild polar bear meat. In 2016, several people were infected with Trichinella roundworms from eating polar bear meat from a local brætter even though the meat had initially passed inspections. As of 2017, Trichinella inspections for seal and polar bear meat sold at brætter is not mandatory. Mexico Some traditional Mexican open-air markets called tianguis, such as the Mercado Margarita Maza de Juárez in Oaxaca, are separated into a wet market (zona húmeda) and a dry market (zona seca). A 2002 study observed a trend that Mexican consumers, especially those in the middle class, increasingly prefer supermarkets for beef purchases as opposed to traditional wet markets. In 2014, a study of Mexican beef retail also noted an ongoing transition from traditional full-service wet markets to self-service meat display cases in supermarkets. In Mexico, conflicts between traditional and modern retailers are handled at the municipal and state levels. Some local zoning rules, such as those in the central districts of Mexico City and Morelia, have prohibited wet markets from operating in urban districts without providing further assistance to the retailers. United States In April 2020, The Hill reported that wet markets were still operating in the United States and that animal rights activists were calling for the closure of wet markets, in addition to their existing calls to close live animal markets and factory farms. Wet markets were common in New York City until refrigeration became commonplace in the 20th century. From the 1990s to 2020, the number of live animal wet markets in New York City nearly doubled. As of 2020, there are more than 80 wet markets in New York City that stock live animals and slaughter them on-demand for customers. They are mostly poultry markets located in outer-borough immigrant communities where they are culturally significant
