My child ate some pepperoni that was sticky, but didn't smell or taste bad, and was before the expiration date. Is that a sign that it might've spoiled early, or was it likely still safe?

    It seems like pepperoni is always a bit sticky; it certainly sticks to itself in the package anyway. I take it you mean more sticky than that?

  • A little bit. They were all stuck together a bit stickier than usual. May 13, 2016 at 3:23
  • Did you just open the package? If not, was the pepperoni refrigerated and in a sealed bag to keep air away?

  • It was refrigerated but not sealed for 2 weeks. Air could get to it. It came in a non resealable bag. May 13, 2016 at 10:47

Pepperoni has quite a bit of fat in it, and it's going to break down over time as it ages in the fridge (just like the meat that went into it). That can result in a sort of tacky feeling to it. You get this in things like beef summer sausage, too. It's always rather dry by the time it spoils, which takes quite a while.

Sticking an uncovered sausage in the back of the ref for a day or so is something many folks do to bring out the spices it contains a bit more prior to cooking. It also tends to come out a little tacky, depending on fat and preservative content. I do this with store-bought Italian sausage to get the fennel and anise a bit more pronounced.

If it doesn't smell acrid or rancid, and feels like pepperoni despite being a little tacky, it's probably fine. When preserved meats go bad a few parts of it start to have an acrid sort of odor, quickly followed by the rest. It's harder to spot initially in chorizo and similar, but bad pepperoni really gives itself away pretty quickly.

Also, taste a small piece. If it's rather sour, you probably don't want to use it.

The stickiness was, regrettably, probably sodium nitrite or a similar preservative. When applied in amounts that don't result in liquid "run-off," it tends to be sticky. I always rinse it off with cold water for aesthetic purposes, but no real precautions are needed.
