Food Standards Agency investigates food origin in the UK
Food samples from England, Scotland and Northern Ireland will be analysed using a technique called stable isotope ratio analysis.
The study aims to check the accuracy of origin claims on food labels for improved consumer confidence.
Samples of food have been taken from foodservice outlets as well as retail and wholesale. More than 100 samples are being tested comprising beef (including burgers), pork, lamb, tomatoes, apple juice and honey.
Stable isotope analysis is a screening method that acts as an indicator of potential fradulent activity. Any results that suggest incorrect labelling will be subjected to an audit of traceability, which will be completed by April alongside the full report of the study.
