Indian Dairy Plant MEP — FSSAI + Codex CAC/RCP 57 + ISO 22000 + 3-A + IDF
A 500,000 LPD integrated Indian dairy plant demands ₹375 Cr MEP capex covering raw milk chilling + HTST + UHT + spray dryer + cheese ripening + ETP with DAF. FSSAI + Codex CAC/RCP 57 + ISO 22000 + USDA 3-A + IDF govern. Three failures FSSAI + USDA 3-A audits catch: CIP common pipework across HACCP zones creating cross-contamination risk, NH3 leak detection only at refrigeration room (need process-zone detection per ASHRAE 15), ETP without DAF failing CPCB FOG < 10 mg/L norm causing closure notice.
Indian dairy plant MEP framework
Indian dairy (Amul/GCMMF, Mother Dairy, Nestle, Britannia, Heritage, Hatsun, Schreiber Dynamix) handles 200 million litres/day milk processed nationally. Standards stack — FSSAI Schedule 4 + Codex Alimentarius CAC/RCP 57 (Milk + Milk Products) + ISO 22000 HACCP + ISO 17025 (lab) + BIS IS 1479 + IDF International Dairy Federation + USDA 3-A Sanitary Standards (where exporting). MEP signature — pasteurisation HTST/UHT, sterilisation, CIP (Clean-in-Place), refrigeration -2 to +4°C, packaging line, ETP.

Three Indian dairy MEP failures FSSAI + USDA 3-A audit
- CIP common pipework across zones — Codex + 3-A require dedicated CIP per HACCP zone (raw / pasteurised / culture / packaging). Indian dairies share CIP loops + create cross-contamination + listeria + salmonella risk. Specify segregated CIP at design stage.
- Refrigeration NH3 leak detection missed — IS 660 + ASHRAE 15 require continuous NH3 detection in plant room + automatic shutoff at 100 ppm + 1000 ppm. Indian sites alarm at refrigeration room only — leak migrates into process zone before detection.
- ETP DAF (Dissolved Air Flotation) skipped — dairy effluent FOG (fats oils greases) 800-1200 mg/L. Standard ETP without DAF cannot achieve CPCB FOG < 10 mg/L. Required + capex ₹15-20 Cr — often skipped causing CPCB closure notice.
