At a reputable restaurant the cooks are working on par with nurses when it comes to the kind of food safety you need. Massive amounts of hand washing, sanitizing, and good hand placement practice. I'd trust a competent cook way before some rando's at the grocery store. Mind you, just wash your veg properly, rub down boxes and cans, and you'll mostly be fine. Mostly with boxes of stuff I'd decant into my own tupperware and toss the boxes because there's no easy way to disinfect cardboard. Cans and plastic can be doused in a light bleach solution if needed. Cheaper and just as effective as lysol wipes. More effective actually, in many cases.
