You say that but if people are skint on benefits or a student or whatever and it's cheaper, they'll buy it.
Its as simple as that everyone, if you ignore everything else that factors in to the equation of course.
But lets make it simpler so we dont end up going round and round in circles if YOU dont want to buy chlorinated chicken, you dont have to, I wont, the wife wont, so regardless of whether the option to import chlorinated chicken if there is a market for it, if you choose not to buy it, you wont have to.
If the UK enforces its own standards on chicken production and slaughter (and having worked in that industry and currently for the largest wholesale food supplier on the planet) there is no way that it can be done much cheaper.
The chickens are battery farmed within 50 miles of the factory, they are shipped straight the factory with no stops, straight off the lorry and directly on to the slaughter line, no stopping, no waiting , no delays, it progresses through the factory and is hung up, stunned, bleed, boiled, defeathered, penned, cut up and packaged in around 10 minutes.
There is no way, even accounting for price by volume that it will be cheaper by any considerable margin to kill a chicken in the states, treat it, freeze it, sail it over, and distribute it in the uk cheaper than moy park can do it.
Even if the UK accepts chlorination as a standard, there is no requirement for it as it doesnt save any money, its just an additional cost to current production methods.
