Sea Foods Add Iodine to Eggs and Milk

Ithaca, N.Y., Dec.2.—Experiments that offer a better method of combating goiter were recently described at Cornell University. In tests lasting eight years the iodine content of eggs and milk has been multiplied many fold by feeding hens and cows on seaweed.

The sea is one of the richest sources in the type of iodine that prevents goiter. In one type of sea weed, macrosystis pyrifera, Prof. George W. Cavanaugh of the chemistry department has demonstrated practical ways of getting this sea iodine into two of the most general articles of diet.

The iodine eggs are the first of their kind. Ordinary eggs contain from 50 to 100 parts of iodine per billion of egg. These new Cornell eggs contain 5,000 parts.

One of these eggs is equivalent in iodine to half a live lobster, the richest known sea animal in the goiter preventing substance.

They were obtained from a flock of farm hens near Odessa, N.Y. The chickens were fed on the seaweed and on fish scrap. Two months of this diet added to their regular feed produced the iodine eggs.

For iodine milk only the seaweed is added to the usual grain feed of cows. The result is milk containing 10 to 20 times the usual amount of iodine.

The seaweed is a form of kelp obtained from the southern coast of California. It grows in water 50 to 60 feet deep. Its tops are so massed that marine mowing machines harvest them readily. It retains its sea minerals and other nutritive substances when dried.
