In-Depth Survey Report: Recommendations for Control of Egg Containing Dusts and Mists at Siouxpreme Egg Products, Sioux Center, Iowa

摘要

Aerosol concentrations were highest in the transfer and egg breaking rooms and in the two powdered egg packaging areas The aerosol in the transfer rooms consisted of an egg mist or a water mist that may be contaminated with egg products. In the transfer area, this aerosol arises from a poorly ventilated egg washer. Recycle of the wash water (which was observed to be heavily contaminated with broken eggs) could result in high exposure to egg protein. Improved washer ventilation should minimize the escape of this aerosol. In the egg breaking area, the mist arises from the use of compressed air to remove egg yolks, egg shells, and egg debris from the egg breaking machines. A program of minimizing compressed air pressure and installation of local exhaust of the egg breaking machines will minimize the release of egg-containing aerosols. Improving the packaging process should reduce exposure to egg dust as well as increase employee productivity.
