This article discusses the latest research elucidating the main reason why foodborne pathogens like Salmonella are more resistant to heat inactivation in low-moisture food (LMF) systems, including quantitative data relating thermal treatment temperature and water activity/relative humidity to the log-reduction rate of bacterial pathogens in different LMF. Case studies on pilot-scale thermal treatments for the control of Salmonella in LMF are also presented.
A pervasive trend exists to take larger and more frequent samples to address microbial contamination. This trend has touched almonds and is expected to hit other nut products, which can be considered for aggregated sampling as a solution.
The Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) recently published the report, “Ranking of Low-Moisture Foods in Support of Microbiological Risk Management.”
A University of Arkansas professor received a grant from the U.S. Department of Agriculture’s National Institute of Food and Agriculture to study how bacteria persist in low-moisture food processing environments.
Cronobacter, formerly known as Enterobacter sakazakii, can be found naturally in the environment but survives for prolonged periods in low-moisture foods. Learn what can be done to control this pathogen.
