It's amazing you know. The food standards agency is the body whose job is to protect us all from all manner of bad things which might affect the food We all eat. It took an Irish version of the same body to discover horse meat in British food. So it appears the FSA have been asleep on the job.
I think I can guess when things started going pear shaped. Perhaps it had something to do with their master's obsession will all things weather related:

Funny isn't it? They can protect us from the climate but don't lift a finger if it means getting out of the office and actually checking the standard of food We eat.
