However, it is important to note:
* Horse meat is not widely consumed in the UK. Most people would consider it taboo.
* Horse meat is regulated. The UK has strict regulations around the production, transportation, and labeling of horse meat for human consumption.
* Mislabeling is illegal. It is illegal to mislabel other meat as horse meat. The infamous "Horsegate" scandal in 2013 involved some retailers and suppliers mislabeling beef products as containing horse meat, which sparked a public outcry and led to tighter regulations.
Overall, while eating horse meat is not illegal in the UK, it is uncommon and strictly regulated.
