21 Feb 2022 --- Billionaire activist investor Carl Icahn is pushing McDonald’s to change how it sources its pork, including demands that all US pork suppliers move to “crate-free” pork. Icahn, who owns 200 shares in the fast-food giant, has started a proxy fight with McDonald’s over its treatment of pigs and has nominated two members to its board of directors in a bid to propel animal welfare policies.
