I've been lurking for a bit and finally decided to sign up so I could post. I received the Anova for Christmas, and bought a low end foodsaver. This morning I am about half through my first attempt at sous vide with short ribs. I'm dialed in at 62C, have verified that temp outside of just the Anova reading (I realize there is much back and forth on temp, time but want to avoid discussing that here and just focus on what I've seen) and about 36 hours so far. I peeled back the foil this morning on my water bath vessel and noticed a VERY faint smell of beef. I mean ever so subtle - barely detectable and I have a heightened sense of smell like I'm sure others here do as well. Of course my first thought was that a seal on a bag failed. So, I pulled the bags out of the bath and set them in a dish. I blotted them dry with paper towels and inspected them, including some mild pressure but could not find any breaks in the seals or leaks, nor is there any evidence such as water bath color, etc to further suggest a seal actually failed. However, just to be safe I double bagged them, vac'd and sealed again, and put them back in the bath. Now, here's the weird part I'm posting about. In the glass container in which I placed the original bags I pulled from the bath, there were lots of very small plastic "flakes" - very fine material but definitely from the bags. Has anyone ever seen this? I suppose it's possible that the circulation impeller somehow ground up a bag corner but there were quite a few of these flakes. My concern is really about the inside of the bags and whether I'll open them and find similar flakes. I would be relieved if someone else has seen this and it's an external phenomenon only, given I'm a little worried about this cook having to be discarded.
