Identification and characterization of Bacillus thuringiensis and other Bacillus cereus group isolates from spinach by whole genome sequencing.

ABSTRACT: Bacillus thuringiensis (Bt), used as a biological control agent (BCA), can persist on plants, and from there can be introduced into the final food product. In routine food safety diagnostics, these Bt residues cannot be distinguished from natural populations of Bacillus cereus present in plants and all are enumerated as "presumptive B. cereus." In this study, information on eventual use of Bt biopesticides, brand, application times and intervals provided by three food processing companies in Belgium, were integrated with quantitative data on presumptive B. cereus measured from fresh to frozen food products. This information together with data on genomic similarity obtained via whole genome sequencing (WGS) and cry gene profiling using a quantitativ
