Ceramic plates / dishes for me, too. In UK, some councils are banning the use of wooden platters to serve hot meals in restaurants.
I don't think this is HMG UK-wide legislation as yet, but left to the H&S / Food Standards departments of local councils to decide upon. Certainly in the case of Luton BC, a recent eNewsletter from them reported that during a food safety check on a local ethnic restaurant, the inspector ordered them to STOP using wood platters, on health and hygiene grounds.
The inspector paid a surprise re-visit to the establishment a couple of weeks later, to find that they had completly ignored his order, by still serving hot food on wooden platters. In their newsletter, Luton BC proudly announced that the establishment had been fined £15,000 for breaking local Food Safety regs..
It doesn't take a rocket scientist to realize that all those cuts, cracks, knots, and crevices on a wood platter surface can ALL harbour nasty food-poisoning bacteria, like E.coli, Listeria, Campylobacter, and Salmonella...
How does a restaurant 100% sanitize these wood platters after use? They cannot be put into a high temperature dish washer. Run a blow torch over them, to kill bacteria, perhaps? Truth is, we have NO way of knowing! So stay safe and insist on a proper plate please...
