Letter: In Brief

Sir: Dr Digby James suggests (letter, 22 February) that contamination of UK food plants by American genetically modified food plants cannot be avoided because their seeds can be brought here in the human gut. He cites the tomato, because its seed can survive cooking and eating and, apparently, sewage treatment works. If this were really the case, Dr James would find feral tomatoes on any river bank. Though some visiting politicians might benefit from enemas on arrival, it would be preferable if our own respected the views of those who elected them to office.
