Dr. Alistair Humphrey is a Medical Officer of Health in Canterbury and, as such, he investigates a wide range of health issues. One of these is the correlation between high rates of nitrates found in the water supply and the incidence of bowel cancer, which he’ll be talking about at our Regenerative Farming Conference in March.
A Danish study of 2.5 million people confirmed that nitrate levels above 3.87 mg/1000ml substantially increases the risk of colorectal cancer. Canterbury has over a million dairy cattle making the region one of the densest dairy agro-industrial areas in the world.
With colon cancer being the second most common cause of cancer deaths in New Zealand, Dr. Humphrey has highlighted the need for a New Zealand study to understand the health risks of high levels of nitrates from commercial dairy farming seeping into drinking water.
