Enviromental Impact and Risk of CAFOs

Part of the Emerging Topics in Ecotoxicology book series (ETEP, volume 1)


Although effects of compounds generated from CAFOs on fish and other aquatic organisms have been reported, the unanswered question is if the populations are affected. For the pharmaceuticals, the question is if non-target organism populations are seriously affected, in particular the dung beetle which has positive ecological effects over large areas. The antibiotics are of special concern for the emergence of antibiotic resistance strains. On the other hand, the animals used in domestic husbandry are genetically very similar. For example, all of the cows in Israel are sired from about ten bulls and they are raised in essentially the same 300 cow units. These animals breathe the same and eat many of the same foods and drink the same water as humans. They therefore can be our first line of defense in detecting environmental disruptions. The CAFOs can also be a valuable way of disposing of waste materials from many industries, especially the alcoholic beverages (molasses) and citrus industry (fruit grinds). Poultry manure can be silaged and is a good source of protein and bulk for cattle. Furthermore, the manure produced has become a valuable commodity as interest in organic farming grows and the price of inorganic fertilizers increases.
