In Virginia, many new laws go into effect beginning on July 1 - one such law directs the State Board of Health to enact regulations requiring restaurants to have training and post information about food allergies.
I think this is a good change to ensure that more restaurant employees are knowledgeable about food allergies and can appropriately prepare and handle food ordered by patrons with allergies.
