"U.S. inspectors on Monday started using more sensitive tests to detect antibiotics in pork, part of a stepped-up effort to ensure meat safety after a government report last year suggested consumers might be at risk from harmful drug residues."

"While a small, but growing amount of meat products are touted as being free of antibiotics, most meat isn't.
