Summer food safety checklist: Enjoy every bite of summer safely


Summer’s here and that means backyard barbecues, picnics, beach days and campfire cookouts.
But before you load up the cooler, there’s one thing to keep in mind: warmer temperatures can turn your feast into a fast-track to foodborne illness (food poisoning) if you’re not careful.
Bacteria grow and thrive in the heat, and food safety gets trickier when you’re cooking and eating outdoors. Common causes of foodborne illness include campylobacter, salmonella, E. coli, listeria and norovirus.
Foodborne illnesses — more common than you might think
You may have had a bout of diarrhea, cramps, nausea or upset stomach and put it down to a “bug.” There’s a chance you had a foodborne illness.
According to a 2017 Foodbook Survey, every year in B.C. about 2.6 million people get acute gastroenteritis (infection or inflammation of the stomach and intestines). But only a few thousand infections are ever confirmed in lab tests and tracked in health data. That’s because those with milder symptoms recover at home without seeing a doctor, or don’t get tested at a lab.
The Public Health Agency of Canada estimates about one in eight Canadians—4.6 million people—get sick from foodborne illnesses each year. Foodborne illnesses also cost our economy about $3.7 billion in health-care costs and lost productivity a year.
What causes foodborne illness
Foodborne illness is caused by eating food contaminated with bacteria, viruses and/or parasites. Symptoms usually appear within several hours of eating the contaminated food but can sometimes take several days.
Symptoms can include:
- Stomach cramps
- Nausea
- Vomiting
- Diarrhea
- Fever
Most people recover quickly. But for kids under five, older adults, pregnant people and those with weakened immune systems, food poisoning can be more serious.
Who is most at risk of complications
The age group with the highest rate of foodborne illness are young children ages 1–5. Between May 2020 and May 2025, more than half of all reported E. coli infections in the Interior Health region were in infants and very young children. Rarely, people get very sick from E. coli infections with bloody diarrhea, kidney failure or even death.
Other groups at risk include older people over the age of 60, and those with compromised immune systems, such as those undergoing chemotherapy.
The good news: Most foodborne illnesses are entirely preventable
Preventing foodborne illnesses just takes a little education, preparation and planning.
Use this checklist to reduce your risk this summer and beyond.
- Buy cold and frozen foods last so they stay cold longer.
- Check best before dates, especially on meat, poultry and seafood.
- Use a dedicated, washable reusable bag or bin for transporting raw meat, and label it. Wash bags frequently.
- Double-bag raw meat and keep it at the bottom of your cart to prevent drips from contaminating other groceries
- Keep foods out of the danger zone. Bacteria multiply fastest between 4°C and 60°C (40°F to 140°F).
- When transporting foods for outings, use lots of ice packs and fill your cooler right up—it stays colder that way. Ice packs are better than loose ice as they won’t melt into a bacteria bath.
- Store coolers in the shade and keep the lid closed as much as possible.
- Use one cooler for drinks and another for food to reduce warm-air exposure.
- Pre-chill food before your outing so it is cold before going in the cooler. Marinate meat in the fridge—not on the counter.
- Keep raw meat, poultry and seafood separate from other food items.
- Use leak-proof containers or plastic bags.
- Use clean plates and utensils for cooked food—never reuse ones that touched raw meat.
- Wash hands and surfaces with hot soapy water for at least 20 seconds.
- If there is no sink nearby use hand sanitizer and antibacterial wipes until you can wash with soap and water.
- Bring two sets of utensils and cutting boards to picnics and BBQs: one for raw, one for ready-to-eat foods.
- Wash your produce under running water before packing it if you are camping.
- Scrub down your cooler before and after every use.
- Colour isn’t a reliable sign that meat is cooked—always check the internal temperature by using a digital food thermometer for meat every time.
- Here are some examples of safe internal cooking temperatures
- Poultry (pieces or ground): 74°C (165°F); whole: 82°C (180°F)
- Ground beef: 71°C (160°F)
- Pork: 71°C (160°F)
- Steak or roasts: medium-rare 63°C (145°F) (let rest for 3 minutes)
- Fish: 70°C (158°F)
- Shellfish and crustaceans 74°C (165°C)
- Here are some examples of safe internal cooking temperatures
How to check the temperature of your meat: Take meat off the grill and place it on a clean plate. Insert the digital food thermometer through the thickest part of the meat (for burgers insert through the side of the patty). Once done, clean the thermometer in warm soapy water.
- Cool leftovers fast using shallow containers.
- Don’t leave food at room temperature for more than one hour on hot days.
- When in doubt, throw it out!
- Lakes and rivers can look safe—but might not be. Don’t risk it.
- When outdoors or camping, use only safe (potable) drinking water for cooking, brushing teeth and washing produce.
- Boil untreated water for two minutes or use purification tablets. Filters that remove bacteria and viruses can also be used to treat water (e.g., LifeStraw, Katadyn).
- If algal blooms are present in source water, boiling water does not make it safe—find an alternate source
