This case report highlights the challenges associated with the diagnosis and workplace evaluation of occupationally acquired ultraviolet (UV) radiation-induced photokeratitis and associated skin burns in a group of restaurant workers. UV-C spectrum bulbs were inadvertently shipped and installed in insect light traps. Ocular and dermal symptoms were reported in 18 of 85 restaurant employees to varying degrees of severity over a 2-day period. One patient was formally diagnosed with a chemical burn/irritation of the cornea. More severe symptoms were reported by individuals working in close proximity to the lights. This clinical picture can resemble mass chemical or irritant exposure when multiple individuals are affected, and a multidisciplinary approach was required for rapid identification of the source to limit morbidity. Prevention strategies for similar events should be considered which can include limiting hardware compatibility and improving warning labels.
Keywords: germicidal; photokeratitis; radiation; restaurant; ultraviolet.
