Maybe it's in my head but I would be wondering what kind of health regulations are imposed on products that make trash bags.. I can't imagine they would waste too much time regulating something designed for trash.
I could be wrong..
Around here you can get those 2 gallon zip locs that work quite well. also those big turkey roasting bags would probably work great.
At any rate.. yes, I think anything that will hold the liquid and keep it around the meat will work.
Remember to use a non reactive container.. i.e. no metal buckets or pans.
I get the best results from a 5 gallon bucket bought at Home Depot and cleaned with bleach.
