Abstract:
... The combined use of ultraviolet-C light-emitting diodes (UV–C LED) irradiation and antimicrobial packaging film was used to secure the safety of fresh-cut vegetables. The antimicrobial packaging film was prepared by adding grapefruit seed extract (GSE) and zinc oxide nanoparticles (ZnO) to a blend film of poly(lactide) (PLA) and poly(butylene adipate-co-terephthalate) (PBAT). The GSE and ZnO added ...

Abstract:
... Risk analysis consists of risk assessment (RA), risk management (RM), and risk communication (RC). In most countries, RA and RM of food safety are separated to achieve a high scientific integrity, and typically occur in sequential order. However, in case of a food safety incident, even though being separate processes, RA and RM are performed simultaneously due to great time pressure and expected h ...

Abstract:
... Shiga toxin–producing Escherichia coli (STEC) O157:H7/nonmotile and some non-O157 STEC strains are foodborne pathogens. In response to pork-associated O157 STEC outbreaks in Canada, we investigated the occurrence of STEC in Canadian retail raw ground pork during the period of 1 November 2014 to 31 March 2016. Isolated STEC strains were characterized to determine the Shiga toxin gene (stx) subtype ...

Abstract:
... In Japan, strategies for ensuring food safety have been developed without reliable scientific evidence on the relationship between foodborne diseases and food sources. This study aimed to provide information on the proportions of foodborne diseases caused by seven major causative pathogens (Campylobacter spp., Salmonella, enterohemorrhagic Escherichia coli [EHEC], Vibrio parahaemolyticus, Clostrid ...

Abstract:
... This work reports on a new approach to rapidly and selectively detect and discriminate enzymes of pathogenic from those of nonpathogenic bacteria using a patterned autonomously reporting hydrogel on a transparent support, in which the selectivity has been encoded by the pattern shape to enable facile detection by a color change at one single wavelength. In particular, enzyme-responsive chitosan hy ...

Abstract:
... Contamination of beef products by Shiga toxin–producing Escherichia coli is a concern for food safety with a particular subset, the enterohemorrhagic E. coli (EHEC), being the most relevant to human disease. To mitigate food safety risks, preharvest intervention strategies have been implemented with the aim to reduce EHEC in cattle. One class of interventions that has been widely used in feedlots ...

With the exception of O111, 5 O-types were recorded regularly and at high frequencies (O26: 33.3 %; O157: 33.3 %; O104: 66.6 %; O103: 72.2 %; O145: 94.4 %). Genes for Shiga-like-toxins and intimin we ...

Abstract:
... Genomics is revolutionizing our understanding of biological systems and is providing new opportunities for the dairy industry. Genome sequences are now available for strains of many pathogenic and spoilage bacterial species commonly found in food, including dairy products. This information can be harnessed in the dairy production chain to improve molecular diagnostic methods that are either curren ...
