We should, however, try to view such an invention as positive. For example, eradicating E.coli from some foodstuffs would help protect vulnerable children and old folk. It would mean that salmonella, a major culprit in the 85,000 food poisoning occurrences in 2010, could be brought under better control. Aside from health issues, there would be a huge saving in cost. The £5 billion worth of uneaten food thrown away by households each year could be greatly reduced. People who never throw away food, such as my mother-in-law, a farmer’s daughter brought up during wartime, would come into their own. That piece of roast pork that is never finished will be brought out for meals ad infinitum, I predict, should bisin be all it is cracked up to be.
