Salmonella contamination research. Entomologist (left) and microbiologist using a dissecting microscope to identify which of a fly's internal organs should be examined for Salmonella enteritidis bacterial contamination. This is one of the most common forms of salmonella. Normally transmitted through contaminated food, it causes fever, abdominal cramps, and diarrhoea. In the elderly, infants, and those with weakened immune systems, it can be fatal. This research is being carried out by the Agricultural Research Service (ARS) of the US Department of Agriculture. Photographed in the USA.
