11. FAQ
Q1: What is HACCP for animal feed?
Hazard Analysis Critical Control Points – food safety system required by FSMA (21 CFR 507). Identifies and controls hazards (metal, pathogens, chemicals).
Q2: Is HACCP required for feed mills?
Yes – FSMA (FDA) requires feed mills to have HACCP plan (21 CFR 507). Compliance mandatory for US feed mills.
Q3: What are CCPs in a pellet line?
Critical Control Points: magnetic separation (metal), steam conditioning (Salmonella kill), metal detection (finished product).
Q4: What temperature kills Salmonella in feed?
80-85°C for 30-60 seconds. Steam conditioning required.
Q5: Do I need a magnetic separator?
Yes – CCP for metal fragment control. Required by FSMA.
Q6: Do I need a metal detector after pelleting?
Recommended (not mandatory). Auto reject diverter. Provides final check.
Q7: What is a chart recorder?
Records temperature over time. Proof that CCP (steam conditioning) was within limits. Required for FSMA.
Q8: What stainless steel grade for HACCP?
304 stainless steel (minimum). 316 for corrosive ingredients.
Q9: Do I need a HACCP plan document?
Yes – written plan required by FSMA. Identify hazards, CCPs, critical limits, monitoring, corrective actions, verification, records.
Q10: What is FSMA?
Food Safety Modernization Act (US law). Requires preventive controls for animal feed (21 CFR 507).
Q11: What is the difference between HACCP and GMP?
GMP is Good Manufacturing Practice (sanitation, equipment). HACCP is hazard analysis (CCPs). Both required for FSMA.
Q12: How often to clean magnetic separators?
Daily (at least). Document in log. Weigh collected metal monthly.
Q13: How often to test metal detector sensitivity?
Daily (before production). Use test pieces (ferrous, non-ferrous). Document.
Q14: How often to calibrate temperature sensors?
Every 6 months (or per supplier recommendation). Document calibration.
Q15: What is the cost of HACCP compliance?
Equipment: +30-50% over standard line (stainless steel, steam conditioner, magnets, metal detector). Documentation: $5k-20k for HACCP plan development.
