I also just received my APC as a gift but from what i've been reading here it is not recommended.
1, You don't know how the package is sealed. Is it glued or heat sealed?
2, Are there any moisture absorbing pads in the package?
3, Are there any glued on store labels on the package that might melt in the hot bath and gum up your Anova?
The bag it is sealed in is probably food safe but the best bet is to put it in another bag to cook.
