Warmer temperatures are increasing the risk of widespread salmonella outbreaks, according to a new study. The research found that specific weather combinations create perfect storms for salmonella transmission.
The study analyzed 144,703 confirmed cases of salmonella in England and Wales between 2000-2016, using data from the UK Health Security Agency. It examined the timing of outbreaks in relation to 14 weather-related factors, testing how these conditions affected reported cases.
The key drivers of an increase in salmonella cases were air temperature above 50°F, relative humidity, dewpoint temperature between 44.6°F-50°F, and longer daylight hours (12-15 hours). Rising temperatures, increased humidity, reduced rainfall, and longer days were also linked to higher salmonella cases.
Climate change is expected to further increase the risk of salmonella outbreaks, according to researchers. However, more studies are needed in different climate zones to confirm how environmental factors influence the bacteria in other parts of the world.
The study provides a valuable tool for predicting future risks and tailoring interventions, particularly in the context of climate change. It also highlights the importance of food safety practices regardless of weather conditions.
