The FDA’s Ten Foodborne Illness Risk Factors, in Plain English

Most restaurant inspection reports mix two kinds of finding. One kind is tied directly to people getting sick. The other is maintenance and housekeeping. The labels vary by jurisdiction — critical, priority, priority foundation, major, core — but the underlying distinction is national.

The Food and Drug Administration’s Retail Food Risk Factor Study measures ten practices chosen because the Centers for Disease Control and Prevention commonly identifies them as contributing factors in foodborne illness outbreaks. Those ten are what this Note is about. They are also what your local inspector is trained to weight most heavily, even when the public report shows only a grade or a single score.

Why these ten outrank everything else on the report

A cracked floor tile, an unlabelled dry-store bin, or a missing thermometer in a pantry can pad a score and still leave a kitchen that does not make people ill. A single cold-holding failure, a bare hand on ready-to-eat food, or a cooling step that never leaves the danger zone is a different class of problem.

The number on the report tells you how the day went. The risk-factor list tells you whether the kitchen is safe. If you read only one part of a report, read that list. If the same risk factor appears on two consecutive visits, it usually changes how the next inspector reads your file.

The ten practices, one by one

These headings match the observations FDA specialists make in the Retail Food Risk Factor Study. Exact temperatures and time limits are set by the food code edition your jurisdiction has adopted — those numbers are not printed here on purpose. Use your state page for the local figures.

1. Employee handwashing

When, how long, and at which sink. The designated hand sink — not the prep sink, not the three-compartment sink — stocked with soap and single-use towels, reaching warm water, used after raw protein, after face or phone contact, and on return to the line. Still the most-cited practice in American restaurants, and usually the cheapest to fix.

2. Bare hand contact with ready-to-eat food

Anything that will not be cooked again: garnishes, bread, sandwich builds, salads, ice. Prevented with utensils, deli tissue, or single-use gloves. Gloves worn for an hour are a hand that has not been washed for an hour — change them between tasks.

3. Cross contamination

Raw protein stored above or beside ready-to-eat food; shared boards and knives; shared wash water; unwashed produce staged next to plated food. Storage order in every cooler matters as much as what happens on the cutting board.

4. Cleaning and sanitizing food contact surfaces

Correct chemical, correct concentration, correct contact time — and a test strip that proves it. Wiping-cloth buckets made fresh and held at strength. Dish-machine final rinse checked and logged. Effort without concentration is not sanitizing.

5. Cold holding

Refrigerated food held at the temperature the code requires, verified with a calibrated probe rather than a dial on the door. Prep-table wells and salad rails have to hold through a rush, not only at open. Overfilled pans above the load line are the usual culprit.

6. Hot holding

Steam tables and holding cabinets that maintain temperature through a slow service, not just at the start of one. Holding equipment is not cooking equipment — food should already be at temperature before it goes in.

7. Cooling

Cooked or ambient food brought down through the danger zone within the time the code allows. Shallow pans, uncovered or vented — never a deep covered bucket parked in the walk-in. Depth of the pan matters more than most cooks expect. This is the violation many kitchens do not see coming.

8. Date marking

Refrigerated ready-to-eat food labeled so the discard day is obvious to anyone who opens the door, not just to whoever made it. Opened commercial containers count too — deli meats and dairy included.

9. Cooking raw animal foods

Final internal temperatures verified by probe, by item, at the moment of service — not judged by color or clock time. Poultry, ground meat, whole cuts, seafood, and eggs often have different targets. Raw or undercooked items need a consumer advisory on the menu where the code requires one.

10. Reheating cooked foods

Previously cooked food brought back through temperature properly before it enters hot holding. Different rule from cooking, and often missed. Range, oven, or steamer — not the holding well. Soups and sauces need stirring and probes in more than one spot.

The FDA study also observes related practices such as reduced oxygen packaging, use of time as a growth barrier, allergen management, and consumer advisories for raw or undercooked animal foods. Those sit alongside the ten, not instead of them.

How this shows up on a local report

Your county or city may not use the phrase “foodborne illness risk factor.” Look for the tier that means illness risk — critical, priority, or major — and map those lines back to the ten practices above. Good retail practices (floors, walls, lighting, general sanitation) still need closing out. They are not what puts people in hospital on their own.

Repeats matter more than first observations. Three consecutive visits with the same cold-holding or handwashing finding reads as a process failure, not a bad day. Named owners and dated logs are what turn a process failure into a closed item.

What to do with this list

Walk the ten on a normal service day, not a quiet Monday. That is when an inspector will turn up. Close high-weight items first. Assign one person per factor. Read your last three public reports and mark every risk-factor line that repeats.

The ten-minute self-check walks the same ground in roughly the order an inspection runs. It stores nothing and it is not sent anywhere. How inspections work places these ten inside the wider system of model codes and local enforcement. Look up your state for the temperature and time numbers that apply at your address.
