Just a small number of beef and meat production companies control the bulk of the global meat industry – including a handful of privately owned companies – and the biggest have their headquarters in just five countries. These firms are involved in the slaughter of massive numbers of animals each day, processing the meat to be transported globally. This domination of a huge part of the human food chain (think steak, burgers and everything in between), means that any changes in the industry is represented in the share prices of the companies.
The list below covers established companies that deal in the business of cattle. So no chickens or pigs on this farm. Make sure you DYOR research and don't take this for advice though, there are many factors that can affect a stock.
