<p>Salmonella and Shiga toxin-producing E. coli (STEC) were the most frequently reported organisms.</p>
<p>Findings come from the Health Protection Scotland (HPS), part of Public Health Scotland (PHS), annual surveillance report on bacterial, protozoal and viral outbreaks of infectious intestinal disease in 2019.</p>

This study was conducted to determine the occurrence of foodborne pathogens in greenhouse-based aquaponic and hydroponic systems. Fish feces, recirculating water, roots, and the edible portions of lettuce, basil, and tomato were collected at harvest, and microbiological analyses were conducted for the bacterial pathogens Shiga toxin-producing </span><span class="html-italic">Escherichia coli</span><span> (STEC), </span><span class="html-italic">Listeria monocytogenes</span><span>, and </span><span class="html-italic">Salmonella</span><span> spp. </span></p>

Fresh produce was also a significant source.</p>
<p>The Food and Agriculture Organization of the United Nations (FAO) and World Health Organization (WHO) figures based on 2010 estimates show STEC infections cause more than 1 million illnesses and 128 deaths annually.</p>

<p>The work will cover Shiga toxin-producing E. coli (STEC) in beef, leafy greens, raw milk and cheese produced from it, and sprouts. It could take up to five years to complete the project.</p>
