With most consumer goods, Wal-mart can return unsold merchandise to the jobber or manufactuer. With food, they work with food banks. You probably couldn't pick it from from their dumpsters.
Criticism of Walmart
A food bank or foodbank is a non-profit, charitable organization that distributes food to those who have difficulty purchasing enough food to avoid hunger.
In the United States and Australia, food banks usually operate on the "warehouse" model. They act as food storage and distribution depots for smaller front line agencies; and usually do not themselves give out food directly to the hungry. After the food is collected, sorted, and reviewed for quality, these food banks distribute it to non-profit community or government agencies, including food pantries, food closets, soup kitchens, homeless shelters, orphanages, and schools.
Economy of the United States
Wal-Mart has been subject to criticism by numerous groups and individuals. Among these are labor unions, community groups, grassroots organizations, religious organizations, environmental groups and Wal-Mart customers. They have protested against Walmart, the company's policies and business practices, including charges of racial and gender discrimination. Other areas of criticism include the corporation's foreign product sourcing, treatment of product suppliers, environmental practices"." USA Today., the use of public subsidies, and the company's security policies. Wal-Mart denies any wrongdoing and maintains that low prices are the result of efficiency.
In 2005, labor unions created new organizations and websites to influence public opinion against Wal-Mart, including Wake Up Wal-Mart (United Food and Commercial Workers) and Walmart Watch (Service Employees International Union). By the end of 2005, Wal-Mart had launched Working Families for Wal-Mart to counter criticisms made by these groups. Additional efforts to counter criticism include launching a public relations campaign in 2005 through its public relations website, which included several television commercials. The company retained the public relations firm Edelman to interact with the press and respond to negative media reports, and has started interacting directly with bloggers by sending them news, suggesting topics for postings, and sometimes inviting them to visit Walmart's corporate headquarters. In November 2005, a documentary film critical of Wal-Mart (Wal-Mart: The High Cost of Low Price) was released on DVD.
