STERIS has hygiene hysteria. The firm makes sterilization systems for health care, pharmaceutical, research, and industrial markets. In addition to its sanitizing lotions and soaps, health care professionals use the firm's steam and chemical sterilization systems to sterilize surgical and diagnostic devices. STERIS also makes disinfection systems and infection prevention consumables. The company sells such surgical support products as exam lights, surgical tables, and scrub sinks. STERIS sells its equipment and consumables in more than 60 countries. In North America, its Isomedix unit offers contract sterilization for more than a dozen health care, industrial, and consumer products makers. STERIS acquired UK-based Synergy Health for about $2 billion in 2015.
