GE foods need clinical testing for allergies
All genetically engineered foods on the market should be clinically tested to see if they cause allergies following a UN
report on the safety of genetically engineered foods, Green MP Sue Kedgley said today.
Last month's UN report recognised that food allergies can cause severe and even life-threatening reactions, and said all
genetically engineered foods need to be properly assessed for potential allergenicity.
The report said all genetically engineered food containing transferred genes from sources which are known to be
allergenic should undergo clinical testing.
But Ms Kedgley said all foods which have been genetically engineered should be clinically tested. Modified potato, corn,
canola and soybean products which have undergone no clinical or long-term testing are all on sale in New Zealand.
"Standard allergy tests such as simple skin or blood serum tests need to be carried out on all genetically engineered
foods, as that's the only way to know whether they may cause an allergic reaction in some people.
Food allergies affect two per cent of the population, and up to eight per cent of children under three.
"While allergies may only affect between two and eight per cent of the population, allergic reactions can be severe and
even life-threatening. I am particularly concerned that children may be most at risk," she said.
"In Britain soy allergies increased by 50 per cent in 1998, about the time when Roundup Ready soy first infiltrated the
market. We simply don't know whether these two events were linked, but thorough allergenicity testing and a good
labelling system would make consumers feel a lot safer."
Ms Kedgley said some genes being added to food were derived from plants and animals which were not normally eaten by
humans, such as leeches, mice, daffodils and toads.
"The only way of finding out if people are allergic to these new proteins is by carrying out full clinical trials and
long-term testing. Otherwise we're just blundering ahead in the dark."
