GM testing expert, Dr Andrew Tingey of RSSL, has warned the food industry against overstating claims for the accuracy of GM test results. Dr Tingey claimed: "It is now possible to detect very low levels of GM ingredients in all kinds of foods. However, even the best available methods for quantifying the amounts found have a relative accuracy of plus or minus ten per cent. To rely on any results that do not accept this margin of error is an act of folly. It leaves the industry at risk of breaking the law on labelling."
