Lamb milk replacer produced by Frank Wright Trouw Nutrition in England between February and March of 2011 was withdrawn from the marketplace as of April 13, 2011 due to excess vitamin A. Excess vitamin A is essentially toxic to lambs and can cause excess sweating, dermatitis, urine scald, abnormally stiff gate and recumbancy. Although the vitamin A problem and subsequent recall was limited to a relatively small number of batches produced by the company, several lamb deaths were attributed to the problem and company technical director John Allen said that the company felt “very bad about the incident.”
