Icecreamists, an ice-cream parlour in London's Covent Garden, is selling human breast milk ice-cream for £14 a scoop. The breastmilk is purchased from lactating mothers, and the product (called "Baby Gaga") is intended to raise awareness of breastmilk's deliciousness and encourage more breastfeeding. The milk is pasteurised and flavoured with lemon zest and vanilla pods.

"Some people will hear about it and go yuck – but actually it's pure organic, free-range and totally natural."

Mrs Hiley, who gets £15 for every 10 ounces of milk she donates to the company, said it was a great "recession beater".

"What's the harm in using my assets for a bit of extra cash?" she added.

"I teach women how to get started on breastfeeding their babies. There's very little support for women and every little helps."

Mr O'Connor said health checks for the lactating women were the same used by hospitals to screen blood donors.
