Most restaurants maintain excellent food safety standards. But foodborne illness sickens an estimated 48 million Americans each year, and restaurants are a significant source. You don’t need to be paranoid about dining out, but knowing what to look for can help you make informed decisions about where you eat.
This guide covers the red flags that health inspectors watch for — and that you can spot as a customer — along with practical tools to check a restaurant’s food safety record before you even walk through the door.
How Restaurant Health Inspections Work
In the United States, local health departments conduct regular inspections of food establishments. Inspectors evaluate everything from food storage temperatures to employee hygiene practices. Most jurisdictions use a scoring system — either a letter grade (A, B, C) or a numerical score — and require restaurants to display their most recent grade prominently.
What Inspectors Check
Health inspections typically cover these critical areas:
- Food temperature control — Are hot foods kept above 140°F and cold foods below 40°F?
- Cross-contamination prevention — Are raw meats stored separately from ready-to-eat foods?
- Employee hygiene — Are workers washing hands properly and wearing gloves when required?
- Pest control — Is there evidence of rodents, cockroaches, or other pests?
- Cleaning and sanitization — Are surfaces, equipment, and dishes properly cleaned?
- Food storage — Are items properly labeled, dated, and stored off the floor?
Violations are classified as critical (posing immediate health risks) and non-critical (procedural issues that could lead to problems if not corrected).
How to Check a Restaurant’s Health Inspection Score
Before visiting a restaurant, you can often look up its inspection history online. Here’s how:
Check Local Health Department Websites
Most county and city health departments maintain searchable databases of restaurant inspections. Google “[your city] restaurant health inspections” to find the relevant database.
Use Aggregator Apps
- Yelp — Some locations display health inspection scores directly on restaurant profiles
- Google Maps — Health scores occasionally appear in restaurant listings in select markets
- Haiku — A dedicated app that compiles health inspection data for restaurants in major cities
What Scores Mean
- A or 90–100: Excellent compliance. Minor or no violations.
- B or 80–89: Good overall but some violations noted. Usually correctable issues.
- C or 70–79: Significant violations. The restaurant needs improvement in multiple areas.
- Below 70: Serious concerns. Consider dining elsewhere until the restaurant improves.
Keep in mind that a single inspection is a snapshot. A restaurant that scored a B might have been having an off day. Look at the trend — has the score been declining over multiple inspections, or was it a one-time dip?
Red Flags You Can Spot as a Customer
You don’t need to inspect the kitchen to identify potential food safety issues. Several visible indicators suggest a restaurant may have problems behind the scenes.
Dirty Restrooms
This is the number one observable indicator. If a restaurant can’t keep its public-facing restroom clean, there’s a reasonable chance the kitchen — which customers don’t see — isn’t being maintained either. Check whether the restroom has soap, paper towels or a working dryer, and is generally clean.
Also check whether the restroom has a functioning hand-washing sign. While the sign itself doesn’t guarantee compliance, its absence suggests the restaurant isn’t focused on hygiene standards.
Sticky or Dirty Tables and Menus
Menus are among the dirtiest objects in a restaurant because they’re handled by every customer and rarely cleaned. If the menus are visibly grimy or sticky, it raises questions about overall cleanliness. Similarly, tables that haven’t been properly wiped or are sticky to the touch indicate lax cleaning standards.
Unpleasant Odors
A clean restaurant should smell like food, not garbage, mildew, or cleaning chemicals. Strong chemical odors might indicate someone is trying to mask an underlying cleanliness problem. Musty or sour smells suggest moisture issues that can lead to mold.
Temperature Issues with Food
If your cold dish arrives warm or your hot dish arrives lukewarm, that’s a potential food safety concern. Proper temperature control is one of the most critical factors in preventing bacterial growth. If a restaurant can’t maintain proper food temperatures at the table, there may be issues with food storage temperatures in the kitchen as well.
Visible Pest Evidence
Seeing a cockroach, fly, or mouse in a dining area is an obvious red flag. But also watch for less dramatic signs: small black droppings near baseboards, gnaw marks on food packaging visible from the dining room, or an unusual number of flies near the kitchen entrance.
Employees Not Following Hygiene Practices
Watch whether employees handle food with bare hands (they shouldn’t handle ready-to-eat items without gloves), whether they touch their face or hair and then handle food, and whether they wash their hands after clearing dirty dishes before serving clean plates.
Common Foodborne Illness Risks at Restaurants
Understanding how foodborne illness occurs helps you make safer dining decisions:
Cross-Contamination
Raw meat juices coming into contact with ready-to-eat foods is one of the most common causes of restaurant-related illness. This happens when cutting boards aren’t properly separated, when employees don’t change gloves between handling raw and cooked items, or when raw proteins are stored above ready-to-eat foods in the walk-in cooler.
Temperature Abuse
Bacteria multiply rapidly between 40°F and 140°F — the “danger zone.” Foods that sit in this temperature range for more than two hours become risky. Buffets, outdoor dining events, and restaurants with slow ticket times are most susceptible to this issue.
Improper Handwashing
Despite being the simplest food safety measure, inadequate handwashing remains one of the most cited violations during health inspections. Norovirus, the most common cause of foodborne illness outbreaks in restaurants, spreads primarily through infected food handlers who don’t wash their hands properly.
High-Risk Foods to Be Aware Of
Some foods carry inherently higher risks at restaurants:
- Raw or undercooked shellfish — Oysters, clams, and mussels can harbor Vibrio bacteria and norovirus
- Undercooked ground meat — Bacteria on the surface get mixed throughout during grinding
- Raw sprouts — The warm, humid conditions required for sprouting are also ideal for bacterial growth
- Unpasteurized juices and dairy — Occasionally served at farm-to-table or health-focused restaurants
- Buffet items — Extended holding times increase temperature abuse risk
- Rice — Cooked rice left at room temperature can develop Bacillus cereus toxins that aren’t destroyed by reheating
This doesn’t mean you should avoid these foods entirely — just be more selective about where you order them. A reputable seafood restaurant with a strong inspection record handles raw shellfish very differently than a landlocked diner that occasionally adds oysters to the menu.
What to Do If You Get Sick
If you suspect a restaurant made you ill:
- Seek medical attention if symptoms are severe (bloody stool, high fever, prolonged vomiting, dehydration)
- Report it to your local health department. They investigate complaints and may discover a pattern affecting other diners
- Save any receipts from the restaurant visit
- Note what you ate and when symptoms began. Most bacterial foodborne illnesses present 6–72 hours after exposure
- Contact the restaurant — reputable establishments want to know about potential issues and will often investigate
Dining Out Safely: Practical Tips
- Check inspection scores before visiting a new restaurant
- Trust your senses — if something looks, smells, or tastes off, don’t eat it
- Order well-cooked proteins if you’re uncertain about a restaurant’s food handling practices
- Avoid peak rush times at buffets when food may sit longer between replenishment
- Wash your hands before eating, especially after handling menus
- Ask about allergens and ingredients — a restaurant that takes these questions seriously is typically more careful about food safety overall
Final Thoughts
The vast majority of restaurant meals are perfectly safe. But an informed diner is a safer diner. By checking inspection scores, watching for visible red flags, and understanding how foodborne illness occurs, you can make smarter decisions about where and what you eat. Food safety awareness doesn’t mean living in fear — it means dining with confidence.
