Restaurant depot has a sale this month on bus boxes in their flyer and I was wondering if anyone knows if they would be considered food safe? Could they be used for brining, marinating, food prep and storage? Have a huge piece of corned beef that I want to desalinate before I turn it into pastrami so I thought the size, width, and lack of height of a bus tub would make it easier to do so in my fridge. Could also come in handy for curing bacon, pre rubbing meat, etc. Thanks all!
