"Neigh , this can't be happening" I thought when I first heard it. Still, it will ride a coach and horses through the idea that in the mane the food we eat is  what it says on the packet. The food companies are jockeying for position to say they are doing everything right, and they are on track with that,  not a racetrack though, because they have to cooperate. If I was in the saddle of one of those meat manufacturers, I would take a whip to those who have got it wrong and get out of the starting gates to correct the problem. It seems they are at a gallop to reassure us, but some people will be thrown by the idea of eating horsemeat whereas others will jump fences as they always do and head for the winning post of sinking their teeth into another burger hoping that it is just a straw in the wind. It is odds-on and a good bet that the horsing around with our burgers will end with a fast finish!  Someone will be put out to grass I hope.
