I plan to cook a whole bottom round roast (25lbs.) sous vide. I previously did a 10 lb. piece that was incredibly tender ( 3 days @ 128 degrees ). My question is can I use the original bag that the roast came in. It is heavy gauge and well sealed. I just don’t know if it can take the modest heat or if it is safe to cook in concerning BPA. Does anyone have any info on this?&nbsp;

It depends on your butcher. There’s only one answer and that’s to ask them if their bags are food-safe at that temperature. Have you been buying from them for a while?&nbsp;

It depends on the bag that is used, there are many different opinions on the safety of all plastics. I would normally err on the side of caution and repackage the meat. For anything over an hour or so I will use my own vacuum bags. I do get some steaks that my butcher vacuum seals and I will use his bag after removing the label.

Thanks for the input. Think I’ll stick with my own bags to be safe.
