Horse meat has a long history of causing problems for American politicians.
The Trump administration wants to cut the budget used by the Bureau of Land Management to care for wild horses. Instead of paying to feed them, the Administration proposed lifting restrictions preventing the sale of American mustangs to horse meat dealers who supply Canadian and Mexican slaughterhouses. That has aroused horse lovers, who are committed and formidable opponents of this practice.
“Horse meat, or chevaline, as its supporters have rebranded it, looks like beef, but is darker, with coarser grain and yellow fat…Its supply and demand are irregular, and its regulation is minimal. Horse meat’s cheapness and resemblance to beef make it easy to sneak into sausages and ground meat.”
