In a major advance for the biotech industry a [?] company has won initial permission to grow a special [?] implanted with genes found in human breast milk and saliva. It would be the first time a crop has been used to produce human [?] on a large scale.

The company, Ventria Bioscience, wants to extract the [?] to make a medicine for diarrhoea and possibly to add them to health foods. But consumer groups are [?]. The US Centre for Food Safety's Bill Freece, claims there's a danger of contaminating other crops and possibly [?] human health.

BILL FREECE: I'm really [?] about this because I think there's one, the potential for this [?] to get into the food supply and two, it hasn't been tested, it hasn't gone through a drug review process. So we're dealing with an [?] here, something that could cause harm to human health.

The company insist there's no risk of [?] because the crop will be planted in Kansas where no other rice crops are grown. But with controversy [?], the US Department of Agriculture has yet to give final [?] and there are many bigger regulatory hurdles before the first food with human DNA can be sold to consumers.
