The debate offers us a chance to explain what has been happening. A legal loophole has been created enabling fresh mushrooms to be sold and imported with the idea that people will prepare them—at which point they come within the classification. A problem has been the development of outlets where an attempt is made to get round the law by selling fresh mushrooms, in packets or otherwise. The sellers expect people to prepare the mushrooms, and eventually to be affected by the ingredients that are classified A.
The clause is a response to a relatively new phenomenon of the importation of fresh mushrooms, which are currently not held to be a product or preparation; that practice leads to an anomaly in the system.
