Investigation of the Interactions Between Sanitizers, Surface Characteristics, Washing Conditions, and Bacteria for Improving Microbial Safety of Fresh Produce
POAA exhibited the highest bactericidal ability in the reduction of E. coli O157:H7 populations on cantaloupes and fresh-cut apples, followed by AEW and chlorine. The sequential treatment of AEW followed by Calcium Ascorbate exhibited a good browning control ability and helped to extend shelf life …

A study of detergents and detergent-sanitizers used in in-place cleaning and sanitizing of milk pipe lines on dairy farms
The use of cleaned-in-place milk pipe lines has been increasing for the past several years, particularly in conjunction with the farm bulk tank. It offers an opportunity for increasing operating efficiency by reducing the amount of labor needed for the milking operations. For many dairymen who have …

Sanitizer efficacy against bacteria attached to synthetic meat processing surfaces
The effectiveness of selected sanitizers against bacteria attached to synthetic meat processing surfaces was determined. In initial experiments, in vitro suspensions of Shw. putrefaciens, P. fragi, S. typhimurium, and L. monocytogenes were challenged with sanitizers according to the AOAC Germicidal …

Evaluating the effects of sanitizing drinker lines in commercial broiler houses on the water quality and microbial content in biofilm layers
… to determine the effects of four different sanitizers under commercial broiler house conditions, with three replications over a three flock period. Each flock was grown for 56 days with a 2 week period between each flock. Four oxidative sanitizers were used and assigned to one of four …

Effect of Alternative Household Sanitizing Formulations Including: Tea Tree Oil, Borax, and Vinegar, to Inactivate Foodborne Pathogens on Food Contact Surfaces
… greater desire for using alternative or "green" sanitizers instead of bleach or other common chemical sanitizers. The purpose of this work was to evaluate the effectiveness of one suggested alternative, tea tree oil, as a food contact surface sanitizer. Three foodborne bacterial pathogens …

Development of a Biofilm Model for Evaluating Poultry Drinking Water Sanitation Procedures
… the biofilm community post 48- hour exposure. Sanitizers tested on the coupons included chlorine based product (CBP) (T1) and a hydrogen peroxide based product (HPBP) (T2) dosed to attain residuals in water of 3-5 ppm free chlorine and 25-50 ppm hydrogen peroxide. Control was untreated test …

Sanitizer efficacy towards attached bacteria in a simulated milk pipeline system using pure and mixed cultures
The efficacy of six sanitizers, [chloline (200 ppm), iodophor (2S: ppm), acid anionic (200 ppm), peracetic acid (200 ppm), and fatty acid sanitizer (200 ppm)], was evaluated against bacteria attached to gasket materials. Pseudomonas fluorescens, Yersinia enterocolitica, Bacillus cereus, and …

Disinfection of fresh produce contaminated by enteric viruses and their inactivation mechanisms
… how viruses are inactivated by vegetable sanitizers. However, inactivation mechanisms of viruses by vegetable sanitizers are not fully understood. To fill this knowledge gap, the objective of this study is to understand inactivation mechanisms of viruses exposed to vegetable sanitizers. …

Inactivation of Escherichia coli O157:H7 on raw vegetable sprouts
… E. coli O!57:H7 population reduction by selected sanitizers was also studied. Among the seeds tested, radish seed was the roughest followed by broccoli and alfalfa seeds. A combination of 10% malic acid and 1% TDS (a surfactant) seemed to be as or more effective than 20,000 ppm chlorine in …

Evaluating Risks and Mitigation Measures for Foodborne Pathogens on Harvest Bags
… and (iii) to determine the efficacy of different sanitizers for decontaminating different harvest bag materials. For Obj. 1, harvest bag materials were inoculated with rifampicin-resistant (80ppm; R) E. coli (TVS353) or Salmonella strain cocktail or L. monocytogenes strain cocktail. All surfaces …
