I haven't seen individual bags of the sourdough specials of Utz. We trust Utz labeling and have had no problems. But my concern would be the same as McC's. I always brought back treats for school parties even when the room moms had gone to the trouble of purchasing safe food because the people handing out the food never never washed their hands before serving and because there were often younger siblings sticking their hands in bags, etc. All the parties were held after lunch, so the likelihood that those serving had peanut protein or egg protein (from mayo) on their hands was pretty high.
Now, I know this for testing, but that means you're not going to be there to see if the person serving has washed their hands.
