Essential Guide to Keeping Your Food Safe: Tips for Home and Dining Out
Diligent shopping order, proper chilling, and clean prep routines curb contamination.
Essential Guide to Keeping Your Food Safe
Each year, foodborne illnesses hospitalize over 128,000 people and claim the lives of 3,000 children and adults in the United States alone. Many of these cases stem from unsafe food handling practices that could be prevented at every stage: from supermarket shelves to the kitchen counter, to your favorite local restaurant. This guide offers comprehensive, science-backed strategies to empower consumers in preventing contamination and protecting their health.
Why Food Safety Matters
No matter how comprehensive the laws or thorough the regulations, food contamination risks can never be fully eliminated. Microbes, chemicals, and physical hazards can lurk in produce, meat, and packaged foods. Practicing diligence and good habits in buying, storing, preparing, and eating food is crucial for minimizing risk. Understanding how contamination occurs, and using effective precautionary steps, is the best protection you and your family have.
At the Supermarket: Smart Shopping for Safety
- Prioritize Your Shopping
Begin with canned and packaged goods, then choose fresh produce, and finally pick up raw meat and seafood last. This order minimizes the time perishable foods spend at warmer, unsafe temperatures, and lowers risk of cross-contamination from leaky meat packaging onto other groceries. - Keep Raw Meat Separate
Use plastic bags or separate reusable containers for raw meat, poultry, and seafood to avoid contaminating other foods in your cart or shopping bags. - Check the Produce Cooler Temperature
Ensure that display cases for fresh produce are cold. Most harmful bacteria thrive at temperatures above 40°F (4°C), so look for misting systems and avoid wilted, overly warm items. - Bring a Cooler for Perishables
Especially in hot weather or if you have a long commute, keep a small cooler with ice packs in your car. Perishable foods should never be kept above room temperature for more than two hours, and during summer, that window drops to one hour. - Do Not Assume Organic or Local is Safer
Food grown locally or sold at farmers’ markets is not inherently safer from pathogens or contaminants than food from supermarkets. Foodborne microbes can be present in all types of produce.
At Home: Storage and Preparation
Once the groceries are home, the real work of food safety begins. Here are essential strategies for your kitchen:
Storing Foods Safely
- Set Your Refrigerator and Freezer Correctly
Your refrigerator should be at 37°F (3°C); freezer at 0°F (-18°C). Use appliance thermometers to check these temperatures, as many built-in dials can be inaccurate. - Chill Foods Promptly
Immediately refrigerate perishables after shopping. When serving food buffet-style, do not leave it out for longer than two hours (one hour if room is above 90°F/32°C). - Avoid Overstuffing
Do not overcrowd your fridge; proper circulation keeps all foods cold and reduces uneven temperatures that support bacteria growth.
Cleaning and Hygiene
- Wash Your Hands and Surfaces Regularly
Always clean your hands with hot soapy water before and after handling food—especially raw meat, eggs, and seafood. Likewise, clean all utensils, cutting boards, and countertops thoroughly. - Prevent Cross-Contamination
Store raw meats and seafood in leakproof containers or resealable bags on the bottom fridge shelf, so juices can’t drip onto other foods. Reserve separate cutting boards for raw meats and ready-to-eat items. Never reuse plates or utensils that have touched raw foods unless thoroughly washed. - Don’t Wash Raw Meat or Poultry
Contrary to popular belief, washing raw meats can spread bacteria onto your sink and counters through tiny droplets. Cooking to proper temperatures is the only reliable way to kill pathogens.
What others are reading
Preparing Food Safely
- Defrost Meats Properly
- In the refrigerator, allowing several hours or overnight.
- In a sealed, leakproof bag submerged in cold water, changing the water every 30 minutes.
- In the microwave, only if you plan to cook it immediately.
Never thaw meats on the countertop—room temperature allows bacteria to multiply rapidly.
- Never Use Color to Judge Doneness
Chemical changes can make meat appear cooked before reaching safe internal temperatures. Always use an instant-read food thermometer to check:
| Food | Safe Internal Temperature |
|---|---|
| Ground meat (beef, pork, lamb, veal) | 160°F (71°C) |
| Poultry (whole, parts, ground) | 165°F (74°C) |
| Fresh beef, veal, lamb roasts/steaks | 145°F (63°C) + 3 min rest |
| Pork | 145°F (63°C) + 3 min rest |
| Fish and shellfish | 145°F (63°C) |
Recommended: Use well-reviewed digital instant-read thermometers for best results.
- Wash Fruits and Vegetables
Rinse produce under cold running water, then pat dry with clean paper towels to help remove surface bacteria. Clean your hands and preparation surfaces before touching fresh produce. Do NOT wash pre-washed or ‘ready-to-eat’ greens, as re-washing at home can introduce more pathogens. If in doubt, follow package directions. - Avoid Raw Sprouts
Raw sprouts (like alfalfa, bean, or clover) are notorious for harboring dangerous bacteria due to their warm, humid growing conditions. Only eat sprouts that have been cooked until steaming hot.
Eating Out: Minimizing Risks Away from Home
- Check Restaurant Health Scores
Look up the establishment’s latest health inspection results online via local health departments or official food safety portals. Higher scores indicate better food handling and cleanliness. - Order Carefully-Cooked Meat
Before ordering burgers or other ground meats in non-chain restaurants, ask servers how the kitchen checks for doneness. If the answer does not mention a meat thermometer, consider choosing something else to minimize risk from undercooked meat. - Survey Salad Bars
For salad or buffet stations, observe if servers regularly replace bins (instead of topping up old batches). This ensures older, potentially unsafe foods are removed before serving.
Frequently Overlooked Food Safety Risks
- Kitchen Towels and Sponges
These can be breeding grounds for bacteria if not changed and washed regularly. Use paper towels for wiping up spills and launder kitchen cloths daily. Microwave wet sponges for 1-2 minutes to disinfect, or replace them frequently. - Leftovers and Buffet Foods
Don’t leave any cooked food out at room temperature for longer than two hours—even less in warm environments. Quickly refrigerate leftovers in shallow containers to cool rapidly and evenly. - Unwashed Cans, Jars, and Lids
Dust and germs may sit on the tops of cans and bottle mouths. Rinse and wipe before opening or pouring, especially for foods eaten without cooking. - Reusable Grocery Bags
Wash bags regularly—especially those used for raw meat, as their surfaces can transfer contamination to other foods even after a single use.

Frequently Asked Questions (FAQs)
Q: Can foodborne illness only happen at restaurants or large events?
A: No. Most cases of foodborne illness originate from food that’s prepared and eaten at home. Safe handling and storage at home are just as important as eating out.
Q: Is it true you shouldn’t wash prewashed or ready-to-eat greens?
A: Yes. Additional washing in your kitchen may actually introduce more bacteria from kitchen surfaces. Only wash unwashed, unpackaged produce.
Q: How long can I store leftovers safely?
A: Most cooked leftovers will be safe in the fridge for up to four days. Always reheat leftovers to 165°F (74°C) throughout before eating.
Q: Should I wash eggs before storing them?
A: No. Commercial eggs in the U.S. come pre-washed and sanitized. Re-washing can remove this protective coating, increasing contamination risk.
Q: Are all food thermometers equally accurate?
A: Digital instant-read thermometers are generally more reliable than dial models. Always calibrate and clean your thermometer as directed for best food safety results.
Summary: Building Long-Lasting Food Safety Habits
Safe food handling is built on vigilance and good habits, not guesswork or assumptions. Smart shopping, prompt chilling and storage, separation of raw and ready-to-eat foods, proper cooking, and careful hygiene together create a powerful safety net. Ultimately, these practices help protect you and your family from preventable illness and ensure that every meal is safe and enjoyable.
