Climate change is not just altering weather patterns and ecosystems; it is also posing significant challenges to food production and safety. One critical aspect often overlooked is its effect on preharvest food safety. Preharvest food safety refers to the measures taken to ensure the safety of crops and livestock before they are harvested or processed for consumption. Changes in temperature, precipitation patterns, and extreme weather events associated with climate change can have profound implications for food safety throughout the production process. Changes in temperature and precipitation patterns can create favorable conditions for the proliferation of pathogens such as bacteria, viruses, and fungi [1, 2].

Warmer temperatures and higher humidity levels can accelerate the growth of pathogens on crops and in the soil. Extreme weather events such as floods and storms can lead to contamination of agricultural fields with pollutants, sewage, and other harmful substances, increasing the risk of microbial contamination of crops. Shifts in climate can also impact the distribution and prevalence of pests and vectors that transmit diseases to crops and livestock, further exacerbating contamination risks. Climate change can affect the quality and availability of water resources essential for irrigation and livestock production [3, 4].

Droughts and changes in precipitation patterns can lead to water scarcity, forcing farmers to rely on alternative water sources that may be contaminated or of lower quality Higher temperatures can also promote the growth of algae in surface water bodies, leading to the contamination of irrigation water with toxins such as microcystins, which pose health risks to both humans and animals. Climate change can impact the resilience of crops to environmental stressors and diseases. Variability in temperature and precipitation can alter plant physiology and susceptibility to pests and pathogens, affecting crop yields and quality. Farmers may need to adapt their agricultural practices, such as crop selection, planting schedules, and pest management strategies, to mitigate the impact of climate change on preharvest food safety [5, 6].

This may involve adopting drought-resistant crop varieties, implementing soil conservation practices, and integrating agroecological approaches to enhance resilience. Implementing robust surveillance systems to monitor the presence of pathogens and contaminants in agricultural environments can help identify emerging risks to preharvest food safety. Utilizing technologies such as remote sensing, drones, and sensor networks can facilitate real-time monitoring of environmental conditions and early detection of potential hazards. Promoting sustainable water management practices, such as rainwater harvesting, drip irrigation, and water recycling, can help mitigate the impact of water scarcity and reduce the risk of waterborne contamination in agriculture [7, 8].

Investing in infrastructure for water treatment and purification can ensure the safety of irrigation water and safeguard against microbial contamination. Encouraging the adoption of climate-smart agricultural practices that promote resource efficiency, biodiversity conservation, and resilience can enhance preharvest food safety. Providing training and technical support to farmers on sustainable agronomic practices, soil conservation techniques, and integrated pest management can help build resilience to climate change and minimize contamination risks [9, 10].


Climate change poses significant challenges to preharvest food safety, threatening the security and quality of our food supply. Addressing these challenges requires a coordinated effort involving policymakers, agricultural stakeholders, researchers, and consumers. By implementing proactive measures to enhance surveillance, improve water management, and promote climate-smart agriculture, we can mitigate the impact of climate change on preharvest food safety and ensure a resilient and sustainable food system for future generations.
