Growing sheep were fed silage corn grown on soil amended with 280 dry metric tons per hectare of municipal sewage sludge from Syracuse, New York, for 274 days. Cadmium and zinc were found higher in specific organs of the animals fed sludge-grown corn silage. No significant differences were observed in hepatic microsomal mixed function oxidase activity or proliferation of hepatic smooth endoplasmic reticulum among the two treatment groups but histopathologic changes in hepatic sections of the sheep fed sludge-grown corn silage were observed by electron microscopy.
