Minimum Water Temperature at a Food Establishment Handwashing Sink

Handwashing sinks need more than a faucet and soap. The water supply must support the handwashing procedure required by the code, and the sink must remain accessible and functional.

The 2026 Food Code temperature

Section 5-202.12 of the 2026 FDA Food Code requires a handwashing sink to be equipped to provide water at a temperature of at least 85°F (29.4°C) through a mixing valve or combination faucet. The provision concerns the handwashing sink. Do not confuse it with hot-water requirements for warewashing or other equipment.

Why the sink must be ready for use

A sink with inadequate water, a blocked basin or no soap makes correct handwashing harder and can push employees toward shortcuts. Managers should check that sinks are supplied, accessible and reserved for handwashing, with soap and an approved drying method available.

What managers should inspect

• Confirm the mixing valve or combination faucet provides water at the required minimum temperature.
• Check that the sink is not blocked by equipment or used for food, utensil or mop tasks.
• Keep soap and hygienic drying supplies stocked.
• Repair leaks, clogged drains and malfunctioning controls promptly.
• Verify the state or local code edition and any amendments that apply.

Exam takeaway

For the 2026 FDA Food Code, remember 85°F (29.4°C) minimum at a handwashing sink. The code is a model, so confirm local adoption and keep this requirement separate from other hot-water standards.

The current model-code number is 85°F

The 2026 FDA Food Code changed the model requirement for handwashing-sink water: § 5-202.12(A) requires a sink equipped to provide water at a temperature of at least 29.4°C (85°F) through a mixing valve or combination faucet. Older Food Code editions used 100°F, so a study guide that quotes 100°F may be describing a previous model-code edition. The 2026 model is the current FDA edition, but a state or local jurisdiction may not yet have adopted it. For workplace compliance, confirm the code in force locally.

This is fixture capability, not a handwashing duration

The sink provision asks whether the fixture can provide running water at the required temperature. It does not mean an employee must use hot water at that precise temperature or wash for 85 seconds. Employee handwashing procedure and duration are separate Food Code sections. Keep the fixture condition, the handwashing steps, and any faucet flow-time rule distinct when reading a question. The water also needs to be available through an approved mixing valve or combination faucet; a sink that reaches temperature only by unsafe or improvised control is not a reliable setup.

Inspect more than the thermometer reading

Check that the sink is accessible, supplied with running water, and not blocked by boxes or used for food preparation, utensil washing, or mop disposal. Confirm soap and an approved hand-drying method are stocked. Test the faucet after repairs or temperature complaints and alert maintenance if it cannot reach the required temperature, leaks, or fluctuates unexpectedly. The sink should be conveniently located for employees who need to wash at the required moments; a distant or obstructed sink encourages missed handwashing.

Handle failures before service continues

If a handwashing sink is not working, tell the person in charge immediately. Provide access to another approved handwashing sink if the facility’s layout and local code allow, and arrange repair. Do not direct food employees to use a prep sink as a substitute. If the site cannot provide a required and accessible handwashing facility, the manager must determine whether food operations can continue safely and consult the regulatory authority when needed. Document the outage and confirm the repair restored proper operation.

Example and exam trap

A question specifies the 2026 FDA Food Code and asks the minimum water temperature a handwashing sink must be equipped to provide. The answer is 85°F, not 100°F. If a question names an earlier edition or describes an adopted local code with a different requirement, follow those stated facts. The exam trap is memorizing an older number without checking edition. Always separate the current FDA model from the enforceable local code.

Keep posted procedures current

Managers should review sink inspection sheets and employee training materials when a code edition changes. A posted 100°F checklist may reflect an older model, while local law may still retain that higher requirement. Do not lower a local standard simply because the FDA model changed. Update the operational procedure only after the person in charge or regulatory authority confirms which rule applies at that establishment.

Practical checks and corrective action

The handwashing sink provision also prohibits use of a steam mixing valve at the sink because it can be difficult to control and may create scald risk. The faucet should provide tempered running water through the required mixing valve or combination faucet. Do not bypass the valve or adjust it in a way that exposes employees to unsafe temperatures.

A manager should identify which local code edition applies before revising a temperature log. The FDA Food Code is guidance for adoption; the 2026 model’s 85°F requirement does not automatically repeal a higher state or city requirement. Document the authority’s adopted standard in the operating procedure and train employees against that number.

If hot water supply fluctuates during peak use, test the sink when other fixtures are operating and notify facilities. A single successful check during a quiet period may miss a capacity problem. Protect handwashing access while repairs are underway and use another approved sink if necessary.

Do not confuse the hand sink’s 85°F fixture minimum with the 100°F condition used in the special seven-second chlorine sanitizing provision. Similar temperature numbers can appear in unrelated code sections. Read the noun and section in the question: sink water, sanitizer solution, or warewashing machine.

Scenarios and manager follow-through

A minimum fixture temperature supports a usable sink but does not require scalding water. The 2026 model prohibits steam mixing valves at handwashing sinks and explains that tempered water reduces scald risk. If staff report discomfort or the water fluctuates, have maintenance inspect the mixing valve rather than asking employees to tolerate unsafe temperatures.

Post the locally applicable sink specification, not an outdated national number. During certification study, note that 2026 model questions use 85°F, while older editions and some local codes may differ. In real operations, the regulator’s adoption determines what must be met.
