Question

EDIT: Solved! Thanks to everyone who commented.

I’m talking about [this](https://ch-it.openfoodfacts.org/product/4099200059402/huhn-suss-sauer-aldi)

It’s basically a box that was on the shelf, un refrigerated, that contains cooked chicken. How are they able to keep cooked chicken shelf stable for so long?
