Is it safe to reuse plastic bags used for sous vide? And if it's safe, any special measures apart from the obvious need of cleaning them.

PD: I mean plastic bags specially designated for sous vide that work with a manual vacuum pump like that

There is not safety issue as long as you clean well. It shouldn't be a problem after most cooks. If using high heat...or very long cooks, you might check the integrity of the bag. Otherwise, I suppose you could wash and dry. I mainly use zip lock-type bags and discard after each cook, simply because they are a p-i-t-a to clean.

    I'd add that it's not just the integrity of the bag that counts, but the type of plastic that it's made of. I'm no chemist, but I wouldn't recommend just any bag just because it doesn't break; the wrong type could still be leaching toxins into the food. Seen for example here chefsteps.com/activities/…

  • I mean, in the link provided in the question the manufacturer itself doesn't recommend reusing the bag...
