Severe biological contamination over an open bakery production line — cooling capacity restored and EHS risk eliminated

What this case study covers

A Midwest US commercial bakery's evaporative condenser — with open basin directly above the production area — had yeast, SRB and entrenched biofilm. Product recall, OSHA and Legionella risk were all active.

Inside this case study

• Biological contamination diagnosis: yeast, SRB, biofilm identification
• 3-day weekend cleanup protocol: mechanical + chemical sequence
• Non-phosphate program redesign with ATP and corrosion results
• How to isolate an evaporative condenser from a food production environment
