farm animals

Farm animal exposure has been found to be a risk factor for non-Hodgkin lymphoma. And poultry exposure has been associated with a variety of diseases including thyroid conditions, schizophrenia, senile and pre-senile psychotic conditions, and autoimmune neurological disorders such as myasthenia gravis (see also here).

Due to genetic manipulation, most of retail milk now comes from pregnant cows and is, thus, high in steroid hormones (see also here). Farm animals and/or their flesh have also been found to be contaminated with: Hepatitis E, E. coli, Clostridium difficile (a superbug), drug residues, prions, obesity causing chicken viruses, anabolic steroids, staph (Staphylococcus) bacteria, MRSA (see here, here), and the sarcocystis parasite. Processed meats are high in nitrites, which form carcinogenic nitrosamines. And the avian leukosis/sarcoma virus has been found in 14% of retail egg samples, though the human public health implications are unknown.
