Hines, Tom Jurkiw, Emily Nguyen, Martine Ferguson, Sultana Solaiman, Elizabeth Reed, Maria Hoffmann, Jie Zheng Foodborne outbreaks associated with Shiga toxin-producing Escherichia coli (STEC) contaminated wheat flour have been an increasing food safety concern in recent decades. However, there is little literature aimed at investigating the impact of different flour types on the persistence of STEC during storage and thermal inactivation.

by Tien Ngoc Phuc Nguyen, Son Hai Nguyen, Mai Thi Tran The rapid and accurate detection of pathogenic bacteria is essential for food safety and public health. Conventional detection techniques, such as nucleic acid sequence-based amplification and polymerase chain reaction, are time-consuming and require specialized equipment and trained personnel.

Hendriksen Introduction Salmonella is considered one of the most significant pathogens in public health since it is a bacterium that is frequently linked to food-borne illnesses in humans. Some Salmonella serovars are responsible for outbreaks that are connected to the consumption of animal products.

The study evaluated the effectiveness of animal beddings naturally contaminated by calf manure to reduce E. coli O157:H7 or Salmonella enterica.

by M. E. Coleman, T. P. Oscar, T. L. Negley, M. M. Stephenson Conflicting claims exist regarding pathogen growth in raw milk. A small pilot study was designed to provide definitive data on trends for pathogen growth and decline in raw bovine milk hygienically produced for direct human consumption. An independent laboratory conducted the study, monitoring growth and decline of pathogens inoculated into raw milk.

by Gavin J. Fenske, Jane G. Pouzou, Régis Pouillot, Daniel D. Taylor, Solenne Costard, Francisco J. Zagmutt The serovars of Salmonella enterica display dramatic differences in pathogenesis and host preferences. We developed a process (patent pending) for grouping Salmonella isolates and serovars by their public health risk. We collated a curated set of 12,337 S. enterica isolate genomes from human, beef, and bovine sources in the US.

by Tingting Li, Qinpei Zou, Cheng Chen, Qin Li, Shuquan Luo, Zhifeng Li, Chuan Yang, Di Yang, Zhi Huang, Huadong Zhang, Wenge Tang, Li Qi Bacillus cereus (B. cereus) is a common cause of foodborne illness. An outbreak of acute gastrointestinal illness occurred at two middle schools in a rural region of Chongqing, China, in 2021. This study aimed to elucidate the outbreak’s characteristics, identify risk factors, and determine the source of contamination.

by Rita A. H. Hoving-Bolink, Adriaan F. G. Antonis, Marinus F. W. te Pas, Dirkjan Schokker Goat milk is produced on mainstream and artisanal farms. It was expected that the farm management may influence the microbial population of the milk. Therefore, we investigated the bacterial content and microbiota composition of raw milk in relation to Dutch goat farm management.

by Erika N. Biernbaum, Rohana P. Dassanayake, Eric M. Nicholson, Indira T. Kudva Shiga toxin-producing Escherichia coli (STEC) O157:H7 (O157) is a foodborne pathogen causing human disease ranging from hemorrhagic colitis and hemolytic uremic syndrome to kidney failure, while remaining harmless to cattle, its primary reservoir.

by Julie E. Hernández-Salmerón, Tanya Irani, Gabriel Moreno-Hagelsieb Average Nucleotide Identity (ANI) is becoming a standard measure for bacterial species delimitation. However, its calculation can take orders of magnitude longer than similarity estimates based on sampling of short nucleotides, compiled into so-called sketches. These estimates are widely used. However, their variable correlation with ANI has suggested that they might not be as accurate.
