Food-preparation surfaces and washing produce

Fresh produce can carry soil and microorganisms from farms, transport and handling. Cutting through unwashed skin can move contamination to the edible portion, while a dirty board can transfer pathogens between foods.

Set up the preparation area

• Clean and sanitize food-contact surfaces before use and between incompatible tasks.
• Use separate equipment or an approved cleaning-and-sanitizing step between raw animal foods and ready-to-eat produce.
• Wash hands before handling ready-to-eat food and after any contamination event.
• Keep chemicals, wiping cloths and dirty utensils away from exposed produce.
• Use potable water and a designated food-preparation sink or other approved method for washing produce.

Wash produce safely

Rinse fruits and vegetables under clean running water before cutting, peeling or eating. Rub firm produce with clean hands or a produce brush; remove damaged or bruised areas. Do not use soap, detergent or household bleach on produce because residues may be unsafe and these products are not approved produce washes.

Prevent cross-contamination

Wash and sanitize knives, cutting boards and food-contact surfaces after raw meat, poultry, seafood or eggs and before they contact produce. Store ready-to-eat produce above raw animal foods in a cooler, protect it during preparation, and discard contaminated portions according to the food-safety plan.

Follow the establishment's code

The FDA Food Code model and local rules set requirements for sinks, equipment, cleaning and sanitizing. A produce wash product may be used only when its label and applicable food-contact regulations allow it. Verify local health-department requirements and the establishment's written procedures.

Exam takeaway

Wash produce with potable running water before cutting, keep it away from raw animal foods, and prepare it on clean, sanitized surfaces. Never wash produce with soap or household bleach.

Build a clean-to-ready-to-eat workflow Produce washing works only when the whole sequence protects the edible portion. Start with approved potable water and a clean sink, clean hands, and clean food-contact equipment. Keep unwashed produce, cardboard cases, and soil away from washed produce and from ready-to-eat foods. Wash produce before cutting or peeling when the surface can carry organisms into the interior during cutting. For leafy greens, separate leaves when appropriate and remove damaged or heavily soiled portions. A quick rinse is not a kill step; washing reduces soil and some contamination but does not make unsafe product safe.

Use water and any produce wash exactly as permitted by the Food Code and product label. A chemical sanitizer used on a cutting board is not automatically appropriate for food. Only substances authorized for direct food contact or washing fruits and vegetables may be used, at their labeled concentration and conditions. Do not mix chemicals, improvise a stronger solution, or soak delicate produce in a sanitizer intended for equipment. A commercial wash system must be operated according to the equipment and chemical instructions, including water replacement, concentration checks, and prevention of cross-contamination.

Cross-contamination controls A produce prep sink should be cleaned and sanitized before use and protected from raw animal foods, dirty utensils, mop water, and handwashing. If one sink is used for multiple purposes, verify that the adopted code allows it and that a complete wash-rinse-sanitize-air-dry process occurs between incompatible tasks. A rinse alone does not remove residues or organisms from the prior task. Keep sinks, drainboards, and splash zones in the workflow; clean produce should not be returned to a dirty receiving tub after washing.

Water itself can spread contamination if reused without controls. In a batch wash, soil and microorganisms can transfer from one item to many others. Follow the validated process for water quality, temperature, replacement, and sanitizer where applicable. Do not use a water temperature that draws contaminated water into produce through temperature differentials if a process instruction warns against it. Where produce is packaged as ready-to-eat and labeled as washed, follow the label and the local code; unnecessary re-washing can introduce contamination through hands, sinks, or equipment.

After washing, drain the produce in a clean area and store it in clean, covered containers. Prevent splash from raw poultry or meat and store ready-to-eat food above raw animal foods in refrigeration according to the required hierarchy. Use clean gloves or utensils when handling washed produce, but remember gloves do not replace handwashing. A worker who handles a dirty crate and then portions lettuce has created a contamination path even if the lettuce was previously rinsed.

Scenario: salad prep after raw chicken A cook finishes trimming chicken and wants to use the prep sink for romaine. Stop the switch. Remove the chicken and its packaging, discard waste safely, clean and sanitize the sink and any affected drainboard, wash hands, change contaminated apron or gloves, and use clean equipment. Inspect the faucet handles and nearby surfaces touched during raw preparation. Then wash the romaine under potable running water, remove damaged leaves, drain it in a clean location, and cut it on a clean sanitized board with a clean knife. If ready-to-eat produce was already exposed to raw juices or contaminated equipment, discard affected food when safety cannot be assured; washing after contamination is not a reliable rescue step.

A manager can prevent repeat failures by assigning a dedicated produce sink when feasible, scheduling produce prep before raw proteins, color-coding bins, and including faucets, handles, drainboards, and carts in the sanitation checklist. Verify sanitizer concentration with the proper test kit when sanitizing equipment. The useful record is evidence that controls were checked and corrected, not a substitute for watching the workflow.

Exam distinctions Washing removes visible dirt and reduces contamination; it does not sterilize produce. “Prewashed” is a label claim that must be interpreted under the product instructions and local rules, not an excuse to handle food with dirty hands. A produce wash is not interchangeable with an equipment sanitizer. The FDA Code is a model, so confirm the operative state or local code for sink use and any special process.

Check the process at each handoff A strong procedure assigns responsibility for receiving, washing, draining, cutting, and storing produce. The employee who washes a batch should know which sink and sanitizer are appropriate, how to avoid standing water and splash, and where clean product goes next. The next employee should receive produce in a clean container, not directly in a dirty sink or on a used cutting board. If a batch must be paused, cover and refrigerate it under the facility's safe holding procedure. Labeling can identify when it was prepared and who handled it, but labels do not replace temperature control.

When using a commercial produce wash, measure concentration with the method specified by its label and replace solution at the required interval or whenever visibly dirty. Do not reuse wash water beyond its approved condition. Keep chemical concentrates clearly labeled and stored away from food. If a worker accidentally uses equipment sanitizer on produce, stop service, isolate the batch, and follow the product label and regulator direction for disposal; rinsing may not remove an unauthorized chemical residue.
