Jews who observe kosher practices will only buy products with kashrut certification. Idont recall that Tesco has an organization wide kashrut certification. I dont know if the same can be said for those who observe Halal...I hope so.

So what do Jews have to do with anything? If Jews cared, they would only eat kosher meat. So if some got a mouthful of pig, then they deserve it.

Jews who only eat kosher meat would not have bought beef products in Tesco, unless they were marked as being "kosher" under the supervision of a recognised authority. Therefore, if the products were marked as "beef", but contained horse or pig they would not have been purchased by observant Jews.

...have received their bakshish, it is a kosher pork, so all is sweet.

This is more of an issue foe Muslims than Jews. If you eat a Tesco burger you may as well eat pork.

The only reason for not eating horse meat is because it is not kosher. There is nothing inherently wrong with it (or pork for that matter). After all, some locusts are kosher. Locust on toast anyone?

Many in Scandinavia consume horse meat!

Whenever I read a story like this I am thankful for my decision to keep kosher - despite the effort involved. Most people will be surprised that observant Jews don't care what horrors Tesco puts in their meat, because they would never buy it anyway. Eating a beef hamburger that is from a cow that has not been slaughtered by a shochet is the same as eating a bacon burger. There are no "degrees of unkosher". Treif is treif. Our observant Muslim friends feel the same way - on only buy meat from a halal butcher. The losers in this are not people who don't eat pork, but the general pork eating public who are paying for something they don't get. So Tesco shouldn't single out pork averse public, it should apologize to the public at large.
