Free range and organic farm eggs were studied for microbial contamination which could affect human health. Eggshells were examined for the presence of salmonella, listeria monocytogenes, campylobacter, enterobacteriaceae, staphylococcus, enterococcus, and mesophilic aerobic bacteria. Unfortunately, the data was inconclusive as to which farming style had fewer contaminated eggs, although it did identify that the major contamination differences were due to packing companies and their hygienic conditions. Another aspect to consider with free range and organic farming is that a high density of animals could potentially cause a larger spread of pathogens and therefore it is important to have strict sanitation practices in place.
