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?

I’ll say that the grocery stores in my area have been doing this with meat for several years now. You put the sensor tags on anything that’s likely to be stolen, and abs of beef that are three times the price of five years ago are pretty likely to be stolen.
