On the horse meat debate, I've said in another thread that the clip clop meat will only have improved the affected products.
If the horse meat came from animals bred for consumption, then that comment's true. However, if the meat came from animals that had been used for riding, which is the case in the UK (and in America), then there is a chance that the meat could have traces of a painkiller known as 'bute'. This is the horse equivalent of an Ibuprofen type product and is a pain killer and anti inflammatory.
The problem with bute is that it can be carcinogenic if eaten by humans. This is why the Tesco's incident was pushed as not being a health hazard. Not too sure about the latest Findus findings, or for that matter the half a dozen other cases that will come out over the next few months.
As for kids mealtimes; we all ate the same stuff at the same time until my daughter became a vegan.
Even now, my wife, son (who is 25) and I all eat together.
