Respiratory Symptoms

Questions about respiratory problems were administered as part of a NIOSH-sponsored supplement on occupational health from 1999-2001, and as part of a NIOSH-sponsored supplement on dust in 2002-2003. The most common respiratory problem reported by agricultural workers in 2003 was watery or itchy eyes (8%) with more than a half of the workers who reported these symptoms indicating that their condition was made worse by dust, dirt or chemicals from farm work (62%). A slightly smaller share of agricultural workers reported experiencing a runny or stuffy nose (7%), and more than half of them, also, indicated that the condition was made worse by dust, dirt or chemicals from farm work (52%).
