It may be difficult or impossible to control food quality well enough that every container be mealworm-free. But I expect metrics to be kept so someone can monitor whether or not a supply chain is doing something notably reckless.
Delhaize history
Delhaize started off as a food producer who was regarded as a brand of high quality products. Then they became a big grocery store chain. So of course they sell their own products. And in fact I have never seen Delhaize products sold by other stores.

When I tried to return the rooibos, the CSR asked for a receipt. I did not have one, so he refused. I said: look, it’s brand of the store, so of course it came from here. He argued that it may not have come from /this/ precise store.
I don’t give a shit about getting a 2 euro refund. My whole point was to get the incident recorded so they can look into QA issues. So then I reported this to the food safety authority in Belgium. It’s possible they acted on it, but they sent no acknowledgement. Which effectively signals to consumers they are wasting their time by reporting quality issues.
Is this all normal? I would expect a public health agency to be keen to encourage reports of worms packaged in food.
I think the norm is (sadly enough) to use Twitter. Someone tweets “worm in my food” with a good photo, it gets some attention, then the supplier is forced to try to remedy their embarrassment. This hack doesn’t work for non-Twitter non-Facebook users.

Supply chain and quality assurance concerns are usually handled by the manufacturer and distributor, not the end point grocery stores, though. Anything you return to the grocery store is likely simply thrown out and marked as shrink (operating cost of loss), and never reported to the manufacturer or sent back.
If your goal is to let the manufacturer know about quality issues, you need to do that directly. Not through the end point grocery store. They are likely separate corporate entities under the same parent company, in any case, and have little to no communication between each other. The grocery store would be where you could get a refund or exchange, but that would never reach back to the manufacturer.
I am so much more motivated than the typical consumer. My goal is that when someone else (your typical lazy consumer who may only care to get a refund) returns a can of worms to the grocery store, that the grocer have an obligation¹ to record the food quality/security issue and report it in a way that it gets tracked and ideally in a centralised place.
So indeed as I said, we need to evolve more. We have banks hyper-reporting on mere suspicion of something they perceive as off under excessive AML rules as if there is a gun to their head, yet you bring a real live creepy crawly to a grocer and there is minimal action… as you say getting swept under the rug as shrinkage.
¹ or pressure of some kind.
How it -should- be and what actually happens when you return don’t always match up, sadly. Just giving insight into the reality of how it works from experience working in grocery retail.
