Multiple outlets report that UK supermarkets are introducing additional security measures to reduce in-store theft, including trials that involve fitting GPS trackers to items such as sausages, steak, and beef. The approach described includes placing products in clear plastic security boxes that are labelled as having a GPS tracker. The Independent and The Mirror both cite examples involving low-cost sausages, including a Co-op product priced under £4, with the items being kept in locked packaging within stores. The reports frame the changes as part of wider efforts by retailers to respond to rising shoplifting and increased security demands on high streets. While the articles focus on the use of tracking devices and locked boxes for specific grocery products, they do not provide detailed figures on results or the scale of the trial. Overall, the coverage indicates retailers are testing technology-driven deterrents on certain meat products as part of anti-theft strategies.
