HOCl for Restaurants & Foodservice

The organisms that drive risk here

• Salmonella, E. coli and Listeria in food handling
• Norovirus — the leading cause of foodservice-associated outbreaks
• Cross-contamination between raw and ready-to-eat

Controlling these is not primarily a chemistry problem — it is a consistency problem. The chemistry that fails an audit is almost never the chemistry that was specified; it is the chemistry as actually mixed, at the concentration actually present, on the schedule actually followed. Onsite generation removes the largest single variable by producing the solution at a set concentration every time.

Where it is used

• Food-contact surface sanitation at 50–200 ppm without a potable rinse
• Prep table, board and utensil sanitation
• Produce washing
• Ice machine treatment
• Front-of-house high-touch points
• Restroom sanitation
• Drain treatment for fruit flies and odour

What it replaces

• Quat sanitiser buckets and test strips nobody trusts
• Bleach solutions mixed by eye
• Purchased ready-to-use sprays at foodservice distributor pricing

The honest position: none of these products are useless, and each has applications where it remains the right choice. What changes with onsite generation is the default — the bulk of routine sanitation moves to a chemistry that is cheaper per litre, safer to handle, gentler on equipment and impossible to run out of.

Compliance and audit position

• FDA Food Code sanitiser requirements
• Local health department inspection criteria
• 200 ppm food-contact limit
• Sanitiser concentration verification during inspection

Full citations and downloadable material are on the regulations page, and the sector-specific research citations are collected in the research hub.

Where the money comes from

• Recurring chemical spend eliminated across a multi-site group
• Inspection findings related to sanitiser concentration largely disappear
• Ice machine and drain treatment included at no marginal cost
• Staff training simplified — one solution, one concentration

Implementation SOP

The written procedure for this sector, in sequence:

1. Clean and rinse before sanitising
2. Maintain sanitiser at the specified concentration in buckets and bottles
3. Verify with test strips at open and at each shift change
4. Sanitise food-contact surfaces after each task change
5. Treat drains and ice machines on the weekly schedule
6. Log concentration for the inspector
