How do anti-theft alarms work in grocery stores?

Question

I know that clothing stores items usually have some kind of RFID tags in them. But what about food items in grocery stores, say, a carton of milk? Are tags still embedded in them?

I’ve also read that scanning a barcode esentially deactivates the tag inside. But wouldn’t that mean that people can scan items and then not pay without setting the alarms off?

Generally it’s only high theft items that get tagged like that. I used to be the Asset Protection (Loss Prevention) guy at a Walmart and once a month I would have to look at what we were losing the most of in each department and adjust accordingly. The only “food” items that ever got tagged in my store was liquor. Electronics and cosmetics were always the highest theft items.
