I wouid look at their website for any important info like that.
The hot dogs are Hebrew National Kosher hot dogs. I dont know about the hamburger meat but the company always strives for the higher quality products from potatoes that only come from very particular states that are colder so the potatoes grown there are denser and better quality to the bread that is made solely for Five Guys with no additives or preservatives. I'd be very surprised if the beef was lower quality.
