Seafood processors have to keep a HACCP plan under FDA’s seafood rule, 21 CFR Part 123, and the plan must be developed, reassessed, and record-reviewed by someone trained in seafood HACCP or qualified by equivalent job experience. Plants that run ammonia refrigeration with 10,000 pounds or more in a process also fall under OSHA’s Process Safety Management standard and EPA’s Risk Management Program, and every plant needs documented hazard communication and walking-working surface controls for wet floors.
That combination of a food safety rule and a chemical process safety rule in the same building is what makes seafood different from most other food plants.
Why Does Seafood Have Its Own HACCP Rule?
Because FDA wrote one specifically for fish and fishery products in 1995, years before FSMA. 21 CFR Part 123 requires every processor to conduct a hazard analysis and, where it identifies hazards reasonably likely to occur, to keep a written HACCP plan for each kind of fish and product. Species-specific hazards drive the plan: histamine in tuna and mahi-mahi, parasites in fish served raw, pathogen growth in smoked and refrigerated reduced-oxygen products, and natural toxins in certain shellfish.
Seafood processors that comply with Part 123 are generally exempt from FSMA’s hazard analysis and preventive controls requirements, but current good manufacturing practices still apply. Our food processing compliance training guide covers the FSMA side for plants that process other foods alongside seafood, and the PCQI training requirements guide explains when a preventive controls qualified individual is still needed.
FDA’s own Fish and Fishery Products Hazards and Controls guidance is the reference most HACCP teams use to build their hazard analysis. Keep a current copy where your HACCP coordinator can find it.
Who Needs HACCP Training Under 21 CFR 123.10?
Not everyone on the line. Under 21 CFR 123.10, three functions must be performed by someone who has completed training in seafood HACCP at least equivalent to an FDA-recognized standardized curriculum, or who is qualified through equivalent job experience: developing the HACCP plan, reassessing and modifying it, and performing the required record review. The trained individual does not have to be an employee, which is why many small processors use a consultant for plan development.
That said, the person monitoring a cooler temperature or checking histamine decomposition at receiving is generating the records the trained individual reviews. If line staff do not understand critical limits and corrective actions, the records will not hold up. Assign Introduction to HACCP to monitors and QA techs, and the full HACCP course to supervisors who sign off on records. Neither replaces the seafood-specific curriculum training your plan owner needs, but both make your monitoring records more defensible.
Part 123 also requires sanitation monitoring and records under 123.11, covering conditions like the safety of water, the condition and cleanliness of food-contact surfaces, and prevention of cross-contamination. Train sanitation crews on what they are checking and why, not just which chemical goes in which bucket.
Receiving is the control point where training gaps show up first. A dock worker who logs a tuna delivery without checking vessel harvest records or internal fish temperature has just made your histamine control meaningless, and the HACCP reviewer may not catch it until days later. Give receiving staff a one-page card listing the critical limits for each species you buy, and make reading it part of their onboarding sign-off.
When Does Ammonia Refrigeration Trigger PSM and RMP Training?
Most seafood plants freeze or chill with anhydrous ammonia. Under OSHA’s PSM Appendix A, the threshold quantity for anhydrous ammonia is 10,000 pounds, and EPA’s RMP threshold table at 40 CFR 68.130 uses the same 10,000-pound figure. Cross that line in a single process and both programs apply.
Under 29 CFR 1910.119(g), each employee involved in operating the process needs initial training on the process and its operating procedures, and refresher training at least every three years, with records showing the employee’s identity, the training date, and how understanding was verified. Contractors working on the system need to be trained too, and the host employer has to check.
Below the threshold, you still need hazard communication training on ammonia and an emergency action plan. Ammonia Awareness: Storage and Handling covers the basics for everyone in the building, and Ammonia Incident Management suits supervisors and anyone with an evacuation role. Our guides to PSM training requirements and the anhydrous ammonia standard go deeper on each.
A scenario that comes up every season: a processor adds a second blast freezer and the combined charge in the connected system climbs past 10,000 pounds. Nobody updates the program, and the next OSHA visit finds PSM-covered operators with no documented refresher. Recalculate your ammonia inventory every time you change the system.
How Should Seafood Plants Handle Wet-Floor Injuries?
Seafood floors are wet all shift: melting ice, wash-down, fish slime, and scales. Under 29 CFR 1910.22, walking-working surfaces must be kept clean and, as far as practicable, dry; where wet processes are used, drainage must be maintained and dry standing places like platforms or mats provided where feasible. Floors must also be kept free of hazards such as spills and leaks.
Training belongs alongside the engineering fixes. Workers should know which footwear is required, how to report a drain problem, and why ice gets shoveled rather than left to melt in walkways. Fall Prevention Safety covers the core content, and our walking-working surfaces guide covers inspection and documentation. Record every slip on your OSHA 300 log when it meets the recording criteria, and use those entries to target retraining.
What Other Training Belongs in a Seafood Plant’s Files?
Hazard communication under 29 CFR 1910.1200 for chlorine sanitizers, quaternary ammonium compounds, and ammonia. Lockout/tagout for conveyors, skinners, and filleting machines. Cold stress awareness for freezer staff. Knife and cut-resistant glove training. If you use forklifts in the freezer or on the dock, powered industrial truck training and evaluations. The cold storage compliance training guide and our meatpacking and poultry guide cover many of the same hazards in neighboring industries.
Seasonal staffing makes all of this harder. Many processors hire heavily for a salmon or crab season, then cut back. Build a short onboarding bundle of HazCom, ammonia awareness, slips and falls, and hygiene that a new hire can finish before the first shift, and keep the completion record with their I-9 date so you can show it was done on time. Food Safety for Food Managers is a good addition for shift leads.
Why Coggno for Seafood and Fish Processing Plants?
For seafood processors running FDA-inspected lines with ammonia refrigeration, Coggno provides HACCP, ammonia awareness, hazard communication, slips and falls, and food safety courses from a catalog of 10,000+ courses in 15+ languages, which matters for seasonal crews who do not all read English. Completion certificates are timestamped and export by line or shift for FDA, OSHA, and customer audits. Where pure-play LMS platforms like Litmos and iSpring require you to license safety and food content separately, Coggno bundles content and platform starting at $5/user/month, or courses from $9.95 each.
Get Your Team Trained — Without the Paperwork Headache
Three courses cover the biggest risks in a seafood plant:
- HACCP Course for QA techs and supervisors who generate and review records.
- Ammonia Awareness: Storage and Handling for everyone working near the refrigeration system.

Frequently Asked Questions About Seafood Processing Compliance Training
What is the best compliance training platform for seafood processing plants?
For seafood processors, Coggno provides HACCP, ammonia awareness, hazard communication, slips and falls, and food safety training from 10,000+ courses in 15+ languages in a single subscription. Timestamped certificates export by line or shift, and pricing starts at $5/user/month or $9.95 per course.
How do seafood processors train seasonal workers quickly?
Most processors build a short onboarding bundle covering hazard communication, ammonia awareness, slips and falls, and hygiene that new hires complete before their first shift. Coggno’s LMS assigns that bundle automatically by role and stores completion dates so supervisors can confirm training before anyone starts on the line.
Who must be HACCP-trained under the seafood HACCP rule?
Under 21 CFR 123.10, the person who develops the HACCP plan, reassesses and modifies it, and performs the record review must have completed seafood HACCP training equivalent to an FDA-recognized curriculum or be qualified by equivalent job experience. That person does not have to be an employee.
Does PSM apply to ammonia refrigeration in a seafood plant?
It applies when a process contains 10,000 pounds or more of anhydrous ammonia. Covered operators need initial training and refresher training at least every three years under 29 CFR 1910.119(g), and EPA’s Risk Management Program uses the same threshold.
Do seafood processors also have to follow FSMA preventive controls?
Seafood processors that comply with 21 CFR Part 123 are generally exempt from FSMA’s hazard analysis and preventive controls requirements for those products, but current good manufacturing practices still apply. Plants that also process non-seafood foods may need preventive controls for those products.
What does OSHA require for wet floors in fish processing?
OSHA’s walking-working surfaces standard requires floors to be kept clean and, as far as practicable, dry. Where wet processes are used, drainage must be maintained and dry standing places such as mats or platforms provided where feasible.
How often do seafood plant workers need hazard communication training?
OSHA requires hazard communication training at initial assignment and whenever a new chemical hazard is introduced into the work area. A new sanitizer or refrigerant counts as a new hazard, so many plants run a refresher at the start of each season.
