Iodine levels in UK milk deemed safe


A survey conducted by UK's Food Standards Agency measuring iodine levels in the country's dairy foods has concluded that iodine concentrations in these foods are at safe levels.


Iodine is a trace element found naturally in milk, but animal feed and hygiene products used in the dairy industry could affect its concentration levels.


A total of 350 samples were taken from a range of dairy foods for sale in the UK, including milk (cow, goat and sheep), eggs (duck, goose, hen and quail), cheese, yoghurt and commercial seaweeds. The survey was used to estimate how much iodine people take in when consuming these food groups, and the choice of samples aimed to reflect the range of products available across the UK and their market share.


The results showed that cow milk contained low concentrations of iodine (ranging from 0.30 to 1.00mg/kg) while a small number of goat and sheep milk samples gave slightly elevated levels of iodine.
