Escherichia coli O157:H7 is a virulent foodborne pathogen that causes severe human illness and inhabits the intestinal tract of food animals. Colicins are antimicrobial proteins produced by E. coli strains that inhibit or kill other E. coli. In the present Study, the efficacy of three pore-forming colicins (El, N, and A) were quantified in vitro against E. coli O157:H7 strains 86-24 and 933. Co...

Agricultural water may contact fresh produce during irrigation and/or when crop protection sprays (e.g., cooling to prevent sunburn, frost protection, and agrochemical mixtures) are applied. This document provides a framework for designing research studies that would add to our understanding of preharvest microbial food safety hazards and control measures pertaining to agricultural water. Rese...

Several phenols and related compounds have been shown to have detrimental effects on insects while others have antibiotic activity against fungi which attack higher plants. Insects have also been implicated as contributors to preharvest contamination of corn [maize], Zea mays L, by aflatoxin. The objectives, therefore, were to determine (a) if commercial corn hybrids vary in their silk maysin c...

Preharvest sprouting (PHS) is a key global issue in production and end-use quality of cereals, particularly regions where the rainfall season overlaps harvest. To investigate transcriptomic changes genes affected by PHS-induction ABA-treatment, RNA-seq analysis was performed two wheat cultivars that differ PHS tolerance. A total 123 unigenes related to hormone metabolism signaling for abscisic ...

Antioxidant activity is an important feature for evaluating fruit quality and tolerance to biotic or abiotic stresses. Moreover, antioxidant involved in chilling injury (CI) response postharvest fruit. Chemical elicitors can induce systemic acquired resistance against pathogens, which could partially replace synthetic fungicides. Recently, researchers have found that preharvest sprays with chem...
