Status of DDT in Apple Pomace for Dairy Feeding

Abstract

The DDT content of apple pomace in New York State has been found to be well below FDA's action limit of 0.5 ppm in and on livestock feed ingredients. In view of the uncertainty of DDT transfer to milk at such low concentrations in feeds, recommendations on its use as an energy source in dairy rations can only be based on actual feeding studies. These have been preceded by residue analyses which have established the probable, perennial limits of DDT in pomace at 0.18 ± 0.08 ppm.
