As have £4.75 rumps in the branch in Hornsea, near Bridlington, East Yorks.
The boxes have labels on them that read: “Caution.
“Security device.
“Must be removed at checkout before leaving the store.”
Customer Dylan John, 46, who was visiting the seaside town with his family, told Need To Know: “Talk about a steak out.
“I’ve never seen anything as crazy as lamb chops being protected by GPS tracking.
“I can just imagine boffins at NASA sitting in front of a big screen showing the UK.
“And little dots moving around showing where the lamb cutlets are.
“It’s bonkers.”
The measure comes following a rise in shoplifting amid the cost-of-living crisis in the UK.
Supermarkets have placed relatively low-priced items in security boxes or have tags put on them.
It is to deter hard-up Brits from swiping them off the shelves.
The Co-op has been approached for comment.
