I was really confused by the source of the image being "Interbev", which is the name of a number of, obviously enough, beverage associated companies and organisations. I guess they actually got it from the French Interbev - Interprofession Bétail et Viande (livestock and meat)
A friend of mine on facebook is a weight lifter and he buys food from somebody on facebook called musclefood, they also have a website www.musclefood.com Well they sell horse meat but its been selling out really fast but it might be a way of getting hold of it.
