The rise of factory farms, growing global demand for meat, and indiscriminate use of antibiotics has created new (and/or revived old) health hazards for humans.
Current factory farm methods of raising livestock are creating health hazards: they encourage salmonella and other virulent microbes to develop antibiotic resistance.

The unsanitary and stressful conditions in many industrial livestock operations are breeding new diseases faster than ever before. Even in relatively clean conditions, the large number of animals crowded together can help spread disease.
Lagoons used to collect the manure from the feedlot. Concentrated animal feeding operations create severe pollution because they cannot recycle the huge amounts of manure they produce.
Methicillin-resistant Staphylococcus aureus, aka MRSA, has been linked to intensive pig farming.
Industrial farm animal production is driven by rising global demand for meat.
Consumer demand can change how meat is produced. Seek out meat from local farmers practicing humane, sustainable methods.
