Sir, The article in last week's issue on use-by dates ('Government urged to reform rules on use-by', 9 July) is incorrect in its assumption that government dictates whether any particular food should have a use-by or a best-before date. It is entirely up to the supplier.

But I would urge government to revoke the law that makes it a criminal offence to sell a product after its use-by date has passed. It is clearly unjustifiable for a retailer to be fined, or even imprisoned, for selling a food that is still fit to eat and certainly not unsafe.
