In response to a request from the president of Siouxpreme Egg Products, Inc. (SIC-2017), an investigation was made of occupational exposure to egg products at the facility in Sioux Center, Iowa. Previously at this site workers had been documented to have immunoglobulin-E mediated occupational asthma from airborne egg protein exposure. The exposures to iodide ions, acid gases and total and respirable dust levels were all below the acceptable limits. An analysis of bulk samples of the egg products indicated a protein concentration of 28 to 43 percent. A sample of egg wash water contained 19 milligrams per milliliter (mg/ml) of protein. All but one sample for ambient air total protein concentrations were less than 0.78mg/m3. Ambient air respirable protein concentrations were all less than 0.48mg/m3. Ambient air concentrations of ovalbumin, ovomucoid, and lysozyme were all less than 188, 113, and 3.5 micrograms/cubic meter, respectively. One additional worker was demonstrated to have developed immunoglobulin-E mediated occupational asthma at the time of the study. The authors conclude that a health hazard continued to exist from exposure to airborne egg protein. The authors recommend that specific engineering steps be taken in the transfer room to better control the visible aerosol escaping from the freshly washed eggs from the conveyor entrance and exit to the washer. The practice of using compressed air from a hose to remove dust from one's clothing must be discontinued.
