No specific monitoring is carried out on crops situated in the vicinity of GM crop trials.Separation distances are in place around GM crop trials to minimise the potential for cross-pollination. They do not reflect any doubts about safety; they are used to maintain high levels of purity in adjacent crops and are a recognised method of enabling different crops to co-exist. The Executive's scientific advisers are satisfied that neither cross-pollination involving the variety of GM herbicide tolerant oil seed rape being grown in the farm-scale trials, nor the pollen itself landing on neighbouring crops, poses a threat to human health or the environment. The harvested GM crop and any sexually compatible crops grown within the separation distances surrounding GM crop trials will not enter the human food or animal feed chain.
