Evaluation of a sanitizing washing step with different chemical disinfectants for the strawberry processing industry. Int J Food Microbiol. 2020 Aug 08;334:108810 Authors: Ortiz-Solà J, Abadias M, Colás-Medà P, Sánchez G, Bobo G, Viñas I Abstract Strawberries are often consumed fresh or only receive minimal processing, inducing a significant health risk to the consumer if contamination occurs anywhere from farm to fork. Outbreaks of foodborne illness associated with strawberries often involve a broad range of microbiological agents, from viruses (human norovirus) to bacteria (Salmonella spp. and Listeria monocytogenes). The addition of sanitizers to water washes is one of the most commonly studied strategies to remove or inactivate pathogens on berries as well as avoid cross contamination due to reuse of process wash water. The risk posed with the safety issues of by-products from chlorine disinfection in the fruit industry has led to a search for alternative sanitizers. We evaluated the applicability of different chemical sanitizers (peracetic acid (PA), hydrogen peroxide (H2O2), citric acid (CA), lactic acid (LA) and acetic acid (AA)) for the inactivation of S. enterica, L. monocytogenes and murine norovirus (MNV-1) on strawberries. A control treatment with chlorine (NaClO) (100 ppm) was included. For each sanitizer, different doses (40, 80 and 120 ppm for PA and 1, 2.5 and 5% for H2O2, LA, AA and CA) and time (2 ...

Conclusion Visual estimation had excellent intra-rater reliability in the assessment of neck active rotation and head tilt on infants with congenital muscular torticollis. Visual estimation had acceptable inter-rater reliability in the assessment of neck active rotation but not of head tilt. There was a wide variation in reliability with no correlation between reliability and clinical experience. Assessment tools for head tilt that are more psychometrically robust should be developed.What is Known:• A thorough assessment of infants presenting with torticollis is essential, using assessment tools with robust psychometr...

Abstract PROBLEM/CONDITION: Known foodborne disease agents are estimated to cause approximately 9.4 million illnesses each year in the United States. Although only a small subset of illnesses are associated with recognized outbreaks, data from outbreak investigations provide insight into the foods and pathogens that cause illnesses and the settings and conditions in which they occur. REPORTING PERIOD: 2009-2015 DESCRIPTION OF SYSTEM: The Foodborne Disease Outbreak Surveillance System (FDOSS) collects data on foodborne disease outbreaks, which are defined as the occurrence of two or more cases of a similar ill...

Publication date: October 2017 Source:Food Control, Volume 80 Author(s): Sang-Soon Kim, Dong-Hyun Kang Consumer preference for minimally processed foods has steadily increased for several years, while foodborne outbreaks from under-processed foods continue to be reported worldwide. We investigated the combination effect of ohmic heating with various essential oil components for inactivation of foodborne pathogens in buffered peptone water and salsa. We choose carvone, eugenol, thymol, and citral to combine with ohmic heating, which are registered for use as flavorings in foodstuffs. Combination treatment of ohmic heating ...

Publication date: March 2017 Source:Food Control, Volume 73, Part B Author(s): Sang-Soon Kim, Dong-Hyun Kang Foodborne outbreaks have still been reported worldwide, and acid resistant foodborne pathogens are biological hazards in salsa. We investigated the combination effect of carvacrol and ohmic heating for inactivation of foodborne pathogens in salsa. Salsa samples were subjected to carvacrol, ohmic heating, and the combination treatment to identify any synergistic effect. Quality aspects of salsa such as color and lycopene content were also observed after each treatment. The synergistic bactericidal effect of combinat...
