suraj.sun writes: The maker of "pink slime", Beef Products Inc, suspended operations Monday at all but one plant where the beef ingredient is made(http://www.sltrib.com/sltrib/money/53795345-79/beef-product-company-lean.html.csp), acknowledging recent public uproar over the product has cost the company business. Craig Letch, director of food quality and assurance, said business has taken a "substantial" hit since social media exploded with worry over the ammonia-treated filler and an online petition seeking its ouster from schools. The company, meanwhile, will develop a strategy for rebuilding business and addressing what Letch called misconceptions about the beef the company makes. "We feel like when people can start to understand the truth and reality then our business will come back," he said. "It’s 100 percent beef."
