![]() Post-washing storage of sliced iceberg lettuce (4, 10, 25 ☌) could increase the risk of Enterobacteriaceae as their counts increased during storage even at low temperatures.ĭecontamination Enterobacteriaceae Ionizing radiation Peroxyacetic acid Sodium hypochlorite.Ĭopyright © 2018 Elsevier Ltd. ![]() Therefore, washing shredded iceberg lettuce with combined sanitizing treatment (sodium hypochlorite/sodium hypochlorite, sodium hypochlorite/Kenocid 2100 ®, or Kenocid 2100 ®/Kenocid 2100 ®) for total time of 6 min or exposing it to gamma irradiation (0.6 KGy) can decrease the risk of Enterobacteriaceae (reduction ≥ 2 log). The reduction of Enterobacteriaceae populations on iceberg after gamma radiation (0.6 KGy) was 3 log CFU/g, however, Enterobacteriaceae counts increased post-irradiation storage by 4-5 log CFU/g. The D 10-value of Enterobacteriaceae on shredded iceberg lettuce was 0.21 KGy. Post-treatment growth of Enterobacteriaceae during storage on samples sanitized with sodium hypochlorite and Kenocid 2100 ® was more than on samples washed with water. Sanitization of iceberg lettuce with combined washing/sanitizing treatments reduced Enterobacteriaceae by 0.85-2.24 CFU/g. Combined sanitizer treatments were more effective against Enterobacteriaceae than single washing/sanitizing treatments. Place a tortilla on a plate, add about 3 tablespoons of ground beef in the center and then top with shredded cheeses. Add to online shopping list or grocery cart for Hannaford To Go. To maintain color and prevent wilting, store iceberg lettuce away from high ethylene-emitting produce such as apples, melons and pears. Lettuce is temperature-sensitive and best stored between 32 to 35 degrees Fahrenheit. ![]() Read honest and unbiased product reviews. 2 cups shredded iceberg lettuce (about one-third of a head) found at Hannaford Supermarket. Freshly shredded iceberg lettuce is sold in packs of five-pound bags. No significant difference (P≥ 0.05) among Enterobacteriaceae survival after washing with water or sanitizing with sodium hypochlorite or Kenocid 2100 ® (reduction ≤ 0.6 log CFU/g) were found. Find helpful customer reviews and review ratings for Taylor Farms Shredded Iceberg Lettuce, 8 oz Bag at. pneumonia, Enterobacter cloacae, Klebsiella oxytoca, Pantoea spp., Leclercia adecarboxylata and Kluyvera ascorbate were identified on iceberg lettuce. Sanitization of iceberg lettuce with combined washing/sanitizing treatments reduced Enterobacteriaceae by 0.85-2.24 CFU/g. The objectives of the current study were to i) identify Enterobacteriaceae species on iceberg lettuce, ii) compare the decontamination efficiency of water, sodium hypochlorite (free chlorine 200 ppm), peroxyacetic acid (PA 80 ppm Kenocid 2100 ®) or their combinations and ionizing radiation against Enterobacteriaceae on shredded iceberg lettuce and iii) determine the survival of Enterobacteriaceae post-treatment storage of shredded iceberg lettuce at 4, 10 and 25 ☌, for up to 7 days. Enterobacteriaceae family can contaminate fresh produce at any stage of production either at pre-harvest or post-harvest stages. ![]()
