SIOUX CITY, Iowa (AP) — The beef-processing company that makes the product that critics call "pink slime" continues to struggle more than a year after the initial stories on the lean bits of beef that Beef Products Inc. makes.

The Sioux City Journal reports (http://bit.ly/15YXsIh ) the Dakota Dunes, S.D.-based company lost 80 percent of its business after the uproar over what BPI calls lean finely textured beef.

The meat BPI separates from trimmings with heat and treats with ammonia to kill bacteria used to be widely used in hamburger, but consumers objected to it after media reports depicted it as unsavory.

Many schools and retailers pledged to stop using BPI's products after the "pink slime" reports, and the company saw demand fall to 2 million pounds a week from the previous 5 million pounds a week.

The private company closed three of its four plants, scrapped expansion plans in South Sioux City and eliminated more than 700 jobs, which won't return soon. The plants that closed were in Waterloo, Iowa; Amarillo, Texas; and Garden City, Kansas.

WASHINGTON (AP) — Sunbathers headed to the beach this summer will find new sunscreen labels on store shelves that are designed to make the products more effective and easier to use. But despite those long-awaited changes, many sunscreens continue to carry SPF ratings that some experts consider misleading and potentially dangerous, according to a consumer watchdog group.

A survey of 1,400 sunscreen products by the Environmental Working Group finds that most products meet new federal requirements put in place last December. The rules from the Food and Drug Administration ban terms like "waterproof," which regulators consider misleading, and require that sunscreens filter out both ultraviolet A and B rays. Previously some products only blocked UVB rays, which cause most sunburn, while providing little protection against UVA rays that pose the greatest risk of skin cancer and wrinkles.

Despite that broader protection, one in seven products reviewed by the watchdog group boasted sun protection factor, or SPF, ratings above 50, which have long been viewed with skepticism by experts. In part, that's because SPF numbers like 100 or 150 can give users a false sense of security, leading them to stay in the sun long after the lotion has stopped protecting their skin.

Many consumers assume that SPF 100 is twice as effective as SPF 50, but dermatologists say the difference between the two is actually negligible. Where an SPF 50 product might protect against 97 percent of sunburn-causing rays, an SPF 100 product might block 98.5 percent of those rays.
