I know it should give me pause when a farmer I know and trust as much as tells me that he considers the meat next to worthless. But I've also found, at least in my locale, that producers and processors tend to be set in their ways. On my blog, you can read all about the struggle I had with a local processor just to get him to hang a side of beef for a measly four weeks (search for "battle of the beef"). Even farmers who are going against the grain, and raising heritage breeds on organic pasture, being very experimental and independent, can still be surprisingly conventional in some of their thinking. For instance, it took some searching and persuading to find a local farmer willing to castrate some young rams and raise them for another year, so that I could have some "hogget." The conventional wisdom around here is that "everyone likes their lamb tender and mild-tasting"�ie, not too lamby.
Some of the studies on boar taint that I've turned up find it in only 15% of their samples, suggesting that the problem may be overstated (although some breeds, such as the Duroc, may be more prone). One farmer in the States who has posted the most about this issue has found absolutely no taint in any of his intact boars, up to 30 months of age, and he claims to have tasted more than 100 by now. In a recent blind taste test, he says that 80% of his customers actually preferred the boar meat. Here's the URL for his blog:
http://sugarmtnfarm.com/blog/His recommendation was to be there when the boar is slaughtered and take a soldering iron to the fat. If it's tainted, he says I'll be able to smell it. Then I'll be able to decide whether to take the meat�trimmed of fat�or leave it.
