Dr Sholeem Griffin is a researcher in the Department of Food Sciences and Nutrition and the Centre for Biomedical Cybernetics at the University of Malta. Her postdoctoral studies focus on the development of a hyperspectral imaging system to detect low-level contamination of food products. Here, Dr Griffin discusses how her research could be applied to prevent food wastage.

Reports of the imminent demise of the world’s most popular fruit have surfaced repeatedly over the course of the last decade. Bananas, particularly those grown in large monocultures for the hungry markets of the EU and the US, are vulnerable to a number of diseases, and fears are mounting that the tide is turning against our prevention and mitigation strategies. How much stock should we put in these reports – are the days of the banana truly numbered? Jon Fuhrmann investigates.

A new method for classifying Salmonella strains has been developed by scientists, giving faster turnaround times and greater reliability. Salmonella strains are notoriously difficult to identify, or type; however new research suggests that looking at the sequence differences in three genes, present in all Salmonella strains, results in more accurate, faster discrimination. This may potentially lead to faster identification of outbreak sources by clinical laboratories and public health agencies.

In many instances, the bacteria identified as the cause of these illnesses are strains of Escherichia coli.
