Sanitize vs Disinfect: What’s the Difference?
Keeping your workplace clean isn’t just about appearances - it’s about protecting your customers and your business reputation. In food service, understanding the difference between cleaning, sanitizing, and disinfecting can make all the difference between a safe environment and one that risks contamination and food-borne illness.
So, how do you know when to sanitize and when to disinfect? Let’s break it down.
Why It’s Important to Understand the Difference Between Cleaning, Sanitizing and Disinfecting
Every day, food service workers handle ingredients, equipment, and surfaces that can carry harmful bacteria or viruses. While cleaning removes visible dirt, sanitizing and disinfecting go further to target the unseen threats that cause illness.
Confusing these terms can lead to improper hygiene practices. For example, using a sanitizer when disinfection is required might not fully eliminate pathogens, while using a disinfectant incorrectly could leave behind chemical residues on food-contact surfaces.
By learning the distinctions - and when to apply each step - you can strengthen your food safety practices and protect everyone who enters your kitchen.
What’s the Difference Between Cleaning, Sanitizing and Disinfecting?
Cleaning: The First Step Toward Safety
Cleaning is the process of removing visible dirt, grease, and debris from surfaces. It doesn’t necessarily kill bacteria, but it’s the essential first step before sanitizing or disinfecting.
For example, if you wipe a food preparation surface without using a detergent spray, it won’t be properly cleaned. Any leftover residue can also stop sanitizers or disinfectants from working well. Use detergent and warm water to remove buildup, then rinse before moving to the next step.
Cleaning prepares the surface - sanitizing or disinfecting removes bacteria.
When to clean: Before starting work, before and after preparing food, after handling raw ingredients, after spills, and whenever surfaces or equipment become visibly dirty.
Sanitizing: Reducing Pathogens to Safe Levels
Sanitizing targets the microorganisms that cleaning alone can’t remove. The goal is to reduce the number of pathogens to levels considered safe by public health standards.
In most kitchens, sanitizing is part of the everyday routine. Food-contact surfaces, utensils, cutting boards, and prep counters should all be sanitized regularly, especially after contact with raw foods.
Approved sanitizers are designed for these situations and are safe for use on surfaces where food is prepared. Always follow the manufacturer’s instructions for dilution and contact time to ensure effectiveness.
When to sanitize: After cleaning food-contact surfaces, between preparing different foods, and at the end of each shift.
Disinfecting: When Extra Protection Is Needed
Disinfecting goes beyond sanitizing. It uses stronger agents to destroy or inactivate bacteria, fungi, and viruses - including those that standard sanitizers can’t fully control.
In a food service setting, disinfecting is required when contamination risk is high. For example:
- When equipment or surfaces are exposed to bodily fluids such as blood or vomit
- During a foodborne illness outbreak
- When a health inspector identifies an imminent hazard
Use only approved disinfectants that are appropriate for commercial kitchens, and always follow label directions. Some disinfectants require rinsing with potable water after use, especially on food-contact surfaces, to remove any residue.
When to disinfect: During contamination incidents, illness outbreaks, or when sanitizing alone isn’t enough to ensure safety.
How to Know When to Sanitize vs Disinfect
Choosing between sanitizing and disinfecting depends on the situation:
|
Situation |
Best Option |
Why? |
|
Daily cleaning of food-contact surfaces |
Sanitize |
Maintains safe microbial levels for ongoing use |
|
High-touch areas (e.g. door handles, switches) and restroom facilities |
Disinfect |
Reduces risk of spreading viruses or harmful bacteria |
|
After exposure to blood, vomit, or other bodily fluids |
Disinfect |
Eliminates dangerous pathogens that sanitizers can’t control |
|
Between preparing raw and cooked foods |
Sanitize |
Prevents cross-contamination and foodborne illness |
When in doubt, remember: clean first, then sanitize or disinfect based on the level of risk.
5 Best Practices for Cleaning, Sanitizing and Disinfecting
Building a safe workplace means developing consistent, effective hygiene habits. Here are five best practices every food service team should follow:
1. Use Approved Products
Always choose cleaning products, sanitizers and disinfectants that meet health and safety standards. Look for government-approved identifiers and ensure the products are suitable for use in food service environments.
2. Follow Directions Carefully
Contact time, dilution ratios, and surface compatibility all matter. A disinfectant that sits for too short a time may not kill all pathogens - and one that’s too concentrated could leave harmful residue.
3. Participate in Training
Every staff member should understand the difference between cleaning, sanitizing, and disinfecting. Training helps reduce mistakes, ensures compliance, and builds confidence across the team.
4. Keep Records
Document cleaning, sanitizing, and disinfecting procedures. Regular logs demonstrate due diligence and are useful during inspections and audits.
5. Review and Refresh Regularly
Food safety standards evolve in response to new technologies, cleaning products and current best-practices. Stay current with regulatory updates and reinforce safe practices with other staff members.
Keep Your Workplace Safe - and Your Knowledge Up to Date
Understanding when to sanitize and when to disinfect isn’t just a matter of compliance - it’s a key part of keeping your workplace safe and your customers healthy.
