The Food and Agriculture Organization (FAO) recently released a comprehensive report on indoor farming, also known as controlled environment agriculture (CEA). This approach is seen as a solution for sustainability, climate resilience, and food security.
Indoor farming allows for year-round cultivation of crops like microgreens and leafy greens. While many believe it poses lower food safety risks than traditional farming, the report reveals that risks from microbial contamination are similar for both methods. Common hazards include issues related to seeds, water, and growth materials. Although CEA can reduce outdoor contamination risks, its stable environment might actually allow pathogens to survive longer.
New research indicates that introducing varying environmental conditions in indoor farms could enhance energy efficiency and plant growth, while also potentially reducing the persistence of pathogens. High humidity in CEA makes microbial risks particularly concerning, but chemical risks, like contamination from equipment, also need attention.
Regulatory frameworks have not caught up with the uniqueness of CEA. The practice shares similarities with sprouted seed production, which requires specific interventions like seed disinfection and testing irrigation water. These tailored safety measures could be beneficial in guiding best practices for indoor systems.
Despite its promise, there’s a lot we still don’t know about CEA food safety. The variety in indoor farming setups creates challenges in understanding and managing risks. The report suggests that expert consultations could help identify these risks more clearly. Moreover, utilizing artificial intelligence (AI) and predictive modeling could strengthen risk assessments if consistent data is available.
Key areas for future research include identifying contamination sources in seed production and understanding how different pathogens behave in indoor environments. This will help strengthen food safety practices and foster a safer indoor farming industry.
