Scientists have identified the most influential weather factors and combinations associated with an increase in Salmonella infections.
The study, led by a team of researchers at Surrey’s School of Veterinary Medicine, investigated the impact of different weather factors on the transmission of Salmonella. Their work was supported by animal health company Zoetis and the European Union’s Horizon 2020 research and innovation funding program. Findings were published in the Journal of Infection.
Key factors linked to a predicted increase in salmonellosis cases, regardless of geographical location, included air temperature above 10 degrees C (50 degrees F), relative humidity, reduced precipitation, dewpoint temperature of 7 to 10 degrees C (44.6 to 50 degrees F), and longer day lengths (12 to 15 hours).
