Vision: A world where everyone, everywhere is food secure
Stasiewicz Food Safety LaboratoryHighlights Abstract Aggregative sampling using polymer cloth swabs is a nondestructive, potentially more representative food safety sampling alternative for leafy greens. This study compared aggregative and produce tissue grab sampling to recover aerobic bacteria, total coliforms, and generic Escherichia coli, from commercial romaine grown in 120 m fields, with 5–36 samples at various stages. Aggregative swabs and […]
Abstract Composite produce leaf samples from commercial production rarely test positive for pathogens, potentially due to low pathogen prevalence or the relatively small number of plants sampled. Aggregative sampling may offer a more representative alternative. This pilot study investigated whether aggregative swab samples performed similarly to produce leaf samples in their ability to recover quality […]
Abstract Right now, many concerned parents are probably thinking, how could Cronobacter sakazakii get through the powdered infant formula (PIF) production system? Shouldn’t a food safety monitoring system find such a serious problem? Aren’t those products tested before arriving on shelves? And the very challenging answer is yes, these products were likely tested with a standardized sampling and […]
Abstract Current detection methods for contamination of aflatoxin and fumonisin used in the corn industry are based on bulk level. However, literature demonstrates that contamination of these mycotoxins is highly skewed and bulk samples do not always represent accurately the overall contamination in a batch of corn. Single kernel analysis can provide an insightful level […]
Highlights Abstract Aflatoxin contamination in corn poses threats to consumer food safety and grower economic stability. Current industrial methods for aflatoxin management in corn focus on the bulk aflatoxin level, which can lead to either acceptance of lots with contaminated corn kernels (consumer food safety risk) or rejection of lots with mostly harmless corn kernels (grower economic loss).
