The next twenty years will test our food systems as never before. Climate change disrupts harvests, global supply chains fragment overnight, and emerging pathogens find new routes from farm to fork. To prepare for the unexpected we need a strategy that moves beyond reactive crisis management. We need a roadmap for the next 20 years.

1. Build the digital immune system: We cannot inspect safety into food; we must predict hazards before they emerge. Invest in open-access genomic surveillance of pathogens in irrigation water, wildlife corridors, and transport hubs. Pair this with AI-driven risk mapping that fuses weather anomalies, trade routes, and historical outbreak data. The goal is to make an early-warning dashboard, like a weather forecast for contamination risk, accessible to smallholder farmers and supermarket chains alike.
2. Decentralize and diversify: A single contaminated processing plant should not trigger a continental recall. Support modular, low-cost drying, fermentation, and irradiation units at regional food hubs. For households, promote safe-failure protocols; every kitchen should have a validated method to sanitize questionable produce, for example, with time-temperature pasteurization charts in local languages. Redundancy is the best resilience.
3. Embed safety into circular systems: The unexpected often comes from what we discard, for example, flood-damaged crops entering animal feed, or rinsed pesticides moving from waste to water. Mandate closed loop tracking of high-risk byproducts using blockchain or similar immutable ledgers. Simultaneously, build community safety drills, for example, simulate a sudden toxin alert in school lunches, then document and share learnings publicly.
4. Adhere to Article 27 of the Universal Declaration of Human Rights: the right to share in scientific advancement. That means all protocols, software, and surveillance data must be publicly available, not behind corporate patents. Food safety is a common good, not a competitive advantage.

The unexpected will come. But if we spend the next years building prediction, decentralization, and transparent learning into our food system, we will not merely survive the next crisis, we can emerge safer, wiser, and more united.

Prof Jesus Simal-Gandara is PhD in Pharmacy by the University of Santiago de Compostela (Spain) and Full Prof in Nutrition and Food Science at the University of Vigo (Spain). He specializes in Nutrition (food bioactives and bioactivity) and Food Science (both quality and safety, mainly on food contaminants and packaging safety). He is still leading numerous Spanish, EU, and international research projects in chromatographic and molecular biology methods, together with data analysis, to track agricultural contaminants through the food chain and improve food quality and safety. He was scientific advisor to national and international food safety bodies, including the Spanish Agency for Food Safety and Nutrition (AESAN/AECOSAN) and is still now a FAO/WHO JECFA expert roster.
