Funny that อย (องค์การอาหารและยา?) had not paid attention to the 'current' practice (of clean-and-cook in one process). They should --it is written all over in their areas of responsibilties.
Sigh! The quality of Thailand Public services.

Using steam cooker would separate the cleaning out of cooking. So there is a need to work out a quick cleaning process too. (Currently one dipping in hot --but dirty-- water is considered "clean".)
