Article Synopsis
- Human norovirus (HuNoV) is a major cause of foodborne illnesses globally, and its ability to survive in water raises concerns for food safety, especially in agricultural contexts.
- This study examined how long HuNoV surrogate viruses (murine norovirus and Tulane virus) can remain present and infectious in different types of water used for irrigation after being stored at 16°C for 100 days.
- Results showed that while the two viruses had similar persistence rates, significant variability existed across different water types, with some viruses remaining infectious even after prolonged storage, highlighting ongoing risks for contamination in food production.
Reduced availability of agricultural water has spurred increased interest in using recycled irrigation water for U.S. food crop production.

Determining the probability of and the degree to which these irrigation water sources contain these pathogens is paramount. The purpose of this study was to determine the prevalence of Salmonella enterica and Listeria monocytogenes in alternative irrigation water sources.

- Enteric viruses (EVs) are a major cause of foodborne illnesses, and their persistence in the environment poses contamination risks for agricultural crops, especially through nontraditional irrigation sources like reclaimed and surface waters.
- A 17-month study focused on detecting specific human EVs and indicators in Mid-Atlantic region irrigation waters, using real-time quantitative PCR to assess viral presence and environmental factors.
- The results indicated higher detection rates of EVs and PMMoV in reclaimed water compared to surface water, showing significant correlations with water salinity and highlighting the need for microbiological analysis to ensure food safety.
Article Synopsis
- Climate change is straining freshwater resources, necessitating the search for safe, alternative water sources for irrigation of fresh produce.
- A 26-month study analyzed bacterial contamination levels in water from various sites (like creeks, tidal rivers, and ponds) to assess their safety for irrigation, with many samples showing high levels of total coliforms and enterococci.
- Only a few sites met food safety standards, but implementing recommended measures could enable all tested water sources to safely be used for irrigation within 2 days, highlighting the importance of this research for food safety and agricultural practices.
