A couple of days back in my catering kitchen, there was an incident where a snail was found in one of the patient's salad dish. it was still alive and moving thus it was noticed immediately. As it was sealed, the plate was returned back to us in its original state. My colleague jokingly commented, "wahh so fresh?fresh from the garden!?" we burst out laughing. Another said that it should be an "escargot salad". Lol. How it wasnt spotted by the food handlers and during the plating line was possibly because the plating line goes very fast as there are thousands of meals to be served and since its mass production, the food handlers didn manage to wash it off thoroughly.
