paragraph_text: On public health
  
  Cattle health is at once a veterinary issue (for animal welfare and productivity), a public health issue (to limit the spread of disease), and a food safety issue (to ensure meat and dairy products are safe to eat). These concerns are reflected in farming regulations. These rules can become political matters, as when it was proposed in the UK in 2011 that milk from tuberculosis -infected cattle should be allowed to enter the food chain. Cattle disease attracted attention in the 1980s and 1990s when bovine spongiform encephalopathy (mad cow disease) broke out in the United Kingdom. BSE can cross into humans as the deadly variant Creutzfeldt–Jakob disease; 178 people in the UK had died from it by 2010.
