Supermarket security - is there a tag on EVERY item?

I was in Tesco a week or so back and managed to set off the alarms on the way out, despite having paid for everything. I stood waiting for some security guard to barrel me to the ground, but no staff member seemed to care (notice even) and all I got was amused looks from other customers, presumably glad it was me not them standing there like a mug who'd bollocksed up a gameshow.

But it got me thinking: is there security tagging of some sort on every single item? I get it on expensive items obviously but it never occurred to me it might be on everything. I think the offending item in my case was a small packet of sandwich chicken that cost a couple of quid - I scanned it and bagged it at the self-service, and it was on the screen as scanned but the scales obviously didn't register it as the screen moaned. The Tesco woman appeared and just waved some card at it to silence my plaintive cries, but no other item caused any problem and I definitely didn't trouser a random Toblerone or something. But there's really security on a £2 pack of sandwich chicken?

It's actually quite impressive if it's on everything to be fair, though if it is I'd have thought that alarm would be going off all day long.
