One of Britain's most prominent food scientists has told ITV News that recent changes in regulations sparked the horsemeat scandal. Dr Mark Wolfe, worked for 25 years as a government food Scientist - including The Food Standards Agency.
Today he told us that a change in rules "must have contributed to a large extent to this situation". Dr Wolfe says a shift in policy last year meant a type of burger meat produced in the UK could no longer be used, forcing producers of value meals to buy overseas.
The policy change did not only effect beef - but also lamb, so Dr Wolfe also believes those products should also be checked.
