Drizzle Health is announcing a limited pilot program for MagnaFlow, a new automated inline washwater analyzer designed to give produce processors and food safety teams continuous, real‑time visibility into the microbial loads present in post‑harvest wash systems.

MagnaFlow connects directly to existing wash tanks and measures pathogen and spoilage organism concentrations (including Escherichia coli, Salmonella, and common fungal species) as product moves through the line. The system is designed to deliver results without the enrichment steps that typically add 18–48 hours to conventional food safety testing.

Fresh produce spoilage costs the U.S. supply chain an estimated $30 to $40 billion annually. Despite significant investment in cold chain infrastructure and food safety protocols, operators have historically relied on temperature monitoring and periodic spot‑check testing methods that measure environmental conditions rather than the biological state of the product itself.

MagnaFlow captures and analyzes washwater continuously during standard post‑harvest processing. Rather than testing individual pieces of fruit, the system uses the full volume of washwater from each batch as a comprehensive microbiological sample. Key capabilities targeted for the pilot include:

1. Inline pathogen and spoilage organism detection without enrichment steps
2. Continuous, automated monitoring with no disruption to existing processing lines
3. Lot‑level microbial data delivered in time to inform storage, routing, and shipping decisions
4. Artificial intelligence (AI)‑powered shelf-life prediction based on measured pathogen load rather than temperature alone.

Pilot Program at No Cost to Participants

The MagnaFlow pilot is open to farmers, produce processors, packinghouses, and post‑harvest operations interested in evaluating inline washwater analysis in their facilities. Drizzle Health will cover all participation costs for the pilot period. The program is designed to validate system performance across diverse commodities, facility configurations, and operating conditions.

Pilot participants will receive lot‑level pathogen and spoilage data from their own operations, along with preliminary shelf-life predictions generated by Drizzle Health’s AI‑driven analytics platform.
