Última Movement of Escherichia coli in soil as applied in irrigation water. Repositório Alice SHOCK, C. C.; PINTO, J. M.; LAUBACHER, T. A.; ROSS, R. D.; MAHONY, A. C.; KREEFT, H.; SHOCK, B. M.. The US Food and Drug Administration (FDA) has proposed that If irrigation water exceeds 235 colony-forming units (CFU) of E. coli /100 ml in any one sample or 126 CFU/100 ml in the average of any five consecutive samples, growers would have to cease using that water in any way that directly contacts the surface of fresh produce (FDA 2013). The FDA has proposed that these E. coli levels are an indication of high risk of bacterial contamination of fresh onion (Allium cepa L.) bulbs regardless of the irrigation system. If onion irrigation exceeds 235 CFU, it is not known whether the contaminated water applied by furrow or drip irrigation actually reaches the onion bulb. Soil could filter E. coli and other bacteria before irrigation water reaches onion bulbs....

Ano: 2013 URL: http://www.alice.cnptia.embrapa.br/alice/handle/doc/970550 Onion storage in sterilized new plastic crates compared to storage in old wooden boxes. Repositório Alice SHOCK, C. C.; PINTO, J. M.; KREEFT, H.; SHOCK, B. M. 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...

Ano: 2013 URL: http://www.alice.cnptia.embrapa.br/alice/handle/doc/970555 Survival of Escherichia coli on onion during field curing and packout. Repositório Alice SHOCK, C. C.; PINTO, J. M.; LAUBACHER, T. A.; ROSS, R. D.; MAHONY, A. C.; KREEFT, H.; SHOCK, B. M.. The Food and Drug administration has expressed concern that Onions (Allium cepa) irrigated with water contaminated with high rates of Escherichia coli could harbor E. coli on their surface or interior. On the other hand, since onions contain antimicrobial compounds and field conditions may not be conducive to E. coli survival, the E. coli population on the surface of onions might become negligible through the course of field curing. Further, the relationship between the E. coli in the irrigation water to the E. coli on onion bulbs after field curing, harvest, and packout has not been studied. To determine if E. coli should be of concern in onion production, we sought to measure the die-off of E. coli on onions between the last irrigation and harvest and...
