In food service, you should change gloves every time you switch tasks, and at minimum every four hours during continuous use on the same task. Beyond those two rules, a handful of specific triggers require an immediate change: touching your face, handling your phone, taking out trash, or switching between raw meat and ready-to-eat foods, among others.
The Four-Hour Maximum
Even if you’re working on the same task without interruption, gloves should be replaced at least every four hours. Over time, the material develops micro-tears that aren’t visible to the naked eye, and moisture builds up inside the glove, creating conditions where bacteria multiply quickly. If you’re working in a hot kitchen or sweating more than usual, the effective lifespan of a single pair is even shorter. Four hours is the outer limit, not a target.
Every Task Change Requires New Gloves
The most important rule in food service glove use is simple: one pair of gloves, one task. California health code spells this out clearly, requiring that single-use gloves “be used for only one task, such as working with ready-to-eat food or with raw food of animal origin, used for no other purpose, and discarded when damaged or soiled, or when interruptions in the food handling occur.”
In practice, that means changing gloves when you:
- Switch between raw and ready-to-eat food. Handling raw chicken and then assembling a salad without changing gloves is one of the fastest routes to cross-contamination.
- Move between different raw proteins. Going from raw fish to raw beef counts as a new task.
- Start a completely different duty. If you stop prepping vegetables to restock a cooler or bus a table, you need fresh gloves when you return to food prep.
The underlying principle is that anything touching one food item or surface should never carry over to the next. If you wouldn’t use the same cutting board without washing it first, you shouldn’t use the same gloves either.
Non-Food Triggers That Require a Change
Plenty of actions that seem minor still call for an immediate glove swap. Touching your face, scratching your nose, adjusting your hat or hair net, using your phone, handling money, or taking out the garbage all contaminate gloves just as effectively as handling raw meat. The Institute of Child Nutrition specifically highlights face-touching and phone use as common violations that food workers overlook.
Sneezing or coughing into your gloved hand, wiping down a counter with a cleaning chemical, or picking something up off the floor are equally obvious triggers. If your gloves contacted anything other than the food you’re preparing, they need to go.
Damaged or Soiled Gloves
Any visible tear, puncture, or discoloration means an immediate change, no exceptions. But damage doesn’t have to be obvious. If a glove feels loose, sticky, or unusually wet on the inside, that’s reason enough. Worn-out gloves lose their barrier function well before they visibly fail. When in doubt, swap them out. Gloves are cheap compared to the cost of a foodborne illness outbreak.
Allergen Cross-Contact
Allergen management adds another layer. If you prepare a dish containing peanuts, tree nuts, shellfish, wheat, or any other major allergen, you need fresh gloves before handling food for a different order. The FDA recommends dedicating specific gloves and utensils to allergen-containing products when possible, and changing gloves “as often as necessary to prevent allergen cross-contact.” In dusty environments, even trace residue on a glove can trigger a severe reaction in a sensitive customer.
Some kitchens go further by requiring a full handwash between allergen and non-allergen prep, not just a glove change. If your workplace serves customers with known allergies, this extra step is worth building into your routine.
Do You Need to Wash Hands Every Time?
The general rule is yes: wash your hands before putting on a new pair of gloves. The FDA Food Code has always required handwashing before donning gloves. However, the 2017 update added a practical clarification. If you’re continuing work on the same food product and no contamination has occurred, you can change gloves without washing hands in between. This applies only when you’re swapping gloves for time-based reasons or because of a minor issue like a small tear, and you haven’t touched anything else.
The moment you switch tasks, touch a non-food surface, or handle a different food item, handwashing is required before gloving up again. Think of handwashing as the default and the same-task exception as the narrow carve-out it is.
Quick Reference for Glove Changes
- At least every four hours of continuous use on the same task
- Between every task change, especially between raw and ready-to-eat foods
- After touching non-food surfaces like phones, faces, hair, doors, trash, or money
- When gloves are torn, punctured, or visibly soiled
- After any interruption in food handling, even a short break
- Between allergen and non-allergen food preparation
- After handling cleaning chemicals or sanitizing surfaces
Keep in mind that these are minimum standards based on the FDA Food Code and state regulations. Your local health department or employer may have stricter requirements. Some jurisdictions and restaurant chains mandate glove changes more frequently than every four hours, particularly for high-risk tasks like assembling ready-to-eat items. Always follow whichever standard is more protective.
