organic milk, woman drinking milk

The Soil Association is to further investigate the effect organic milk has on the iodine levels of pregnant women in response to claims it could risk unborn babies.

A spokeswoman said research would be undertaken with Newcastle University later this year in response to the claims - in a study by Reading University - that switching to organic milk during pregnancy could lead to iodine deficiencies in mothers and lower IQs in babies.

Scientists said test results found organic and UHT milk was a third lower in iodine than conventionally produced fresh milk. However, in January tests commissioned by the industry found organic milk was not iodine deficient.
