Manure contamination bad for human and animal health Manure contamination bad for human and animal health by Peter Wallis Controlling animal wastes on the farm can improve both human and animal health.
Water contaminated with manure contains more nutrients and becomes a vector for waterborne disease.
Both can affect animal and human health. The best practice is to water animals from troughs or other watering devices isolated from animal wastes. There are several reasons for this recommendation. First, phosphorus and nitrogen in manure are potent fertilizers for aquatic plants. Excessive algal and rooted aquatic plant growth produces oxygen by photosynthesis when the sun is shining.
