🌾 Project AURA: Aflatoxin Universal Risk Assessment

Predictive Public Health System for Agriculture

An intelligent ecosystem that predicts mycotoxin contamination in agricultural produce before it occurs, providing farmers with actionable interventions to save their harvests and protect public health.

🚨 The Problem

Aflatoxins are invisible killers in our food supply:

🧪 Potent Carcinogens: Produced by fungus on staple crops (maize, groundnuts, rice, chilies)
📊 18% of Indian food samples exceed safety limits
🌾 70.5% contamination in Karnataka groundnuts alone
💀 Health Impact: Liver cancer, childhood stunting, immune suppression
💸 Economic Loss: Millions lost in rejected export shipments
🔍 Invisible Threat: Contamination happens silently during storage

Current Reality: Farmers only discover contamination when crops are rejected - too late to take action.

💡 Our Solution

AURA transforms food safety from reactive to proactive.

We predict aflatoxin contamination 48-72 hours before it happens, giving farmers a critical intervention window to save their harvests.

Three-Pillar Architecture

1️⃣ Predictive AI Engine 🤖

Multi-Stream Data Fusion: Combines satellite imagery (Sentinel-2), real-time weather data, and storage conditions
LSTM Neural Network: Time-series deep learning model trained on contamination patterns
Risk Scoring: Real-time Aflatoxin Risk Score (ARS) from 1-10
Hyperlocal Forecasting: 48-72 hour prediction window with >75% accuracy

2️⃣ Smart Alert System 📱

Progressive Web App: Mobile-first, works offline, installable
Proactive Alerts: "Humidity spike in 48 hours - Risk: 9/10 - Deploy drying beads NOW"
Actionable Intelligence: Not just warnings, but specific preventive actions
Real-time Dashboard: Live risk monitoring with visual indicators

3️⃣ Blockchain Certification ⛓️

AURA-Certified Ledger: Immutable record of preventive actions taken
QR Code Verification: Buyers can verify safety scores instantly
Premium Markets: Creates economic incentive for safe produce
Export Enablement: Meets international food safety standards
