Many successful animal welfare investigations have revealed severe abuses of animals and raised additional concerns about industrial farms, such as the potential contamination of eggs and meat. Such revelations have led to product recalls, decisions by retailers to drop suppliers, legal prosecutions of employees and hard questions posed to the animal agribusiness industry.
It is worth noting that the use of exposés to reveal abuse has a long and storied history in America dating back to journalist Upton Sinclair's 1906 book The Jungle, which uncovered atrocious conditions inside America's meatpacking plants and led directly to the passage of the federal Meat Inspection Act, the Pure Food and Drug Act, and the eventual formation of the federal Food and Drug Administration (FDA).
