Onion storage in sterilized new plastic crates compared to storage in old wooden boxes.
The United States Food and Drug Administration?s (FDA) proposed water rules to implement the Food Safety Modernization Act (FSMA). The FDA has proposed that plastic totes be substituted for wooden bins for the storage on onion bulbs. A preliminary study was conducted to examine the role of wooden storage containers on onion bulb contamination with E. coli. Onions from a furrow-irrigated field using water up to 866 MPN E. coli /100 ml were harvested into 12 old wooden boxes and 12 sterilized new plastic crates. Onions from a drip-irrigated field using water with 0 MPN E. coli /100 ml were harvested into 12 old wooden boxes and 12 sterilized new plastic crates. Onions packed out tended to not have E. coli on the bulb exteriors. The small amount of contamination detected did not appear to be related to the storage containers or irrigation water source.
