Heart patients can avoid food poisoning by avoiding these foods entirely

I used to be a happy person. But then I took a FOODSAFE course.  This certification course is recommended in my province for anybody who handles, prepares or serves food.  It’s very educational, but once you’ve watched those ominous “What Went Wrong?” course videos (about hapless party guests dropping like flies from eating tainted crême caramel), you can become just a wee bit paranoid about foodborne illnesses, often for the rest of your natural life.

That’s why the following basic list of foods to avoid is extremely important.

Food poisoning occurs when you eat food that contains harmful bacteria, parasites, or viruses. It can be severe and sometimes fatal. In fact, The American Society of Clinical Oncology website warns:

 “Foodborne illnesses can be particularly severe if a person has a weakened immune system from cancer treatment or chronic illness like heart disease, or is very old, very young, or pregnant.”

Food can become contaminated when someone infected with a virus (often a norovirus) or other ‘bug’ handles the food. Raw foods are a common cause of foodborne illness. Proper cooking can destroy bacteria, but they can grow even on cooked food if left out too long. Some bacteria, such as listeria, can grow even on foods stored in the refrigerator over time.

That’s what happened last summer when listeriosis killed 22 people of the 57 affected by eating tainted cold cuts produced at a Maple Leaf meat processing plant in Toronto.

In fact, ASCO recommends that you avoid some foods entirely, even if you may have eaten them with no problem in the past, particularly if you have a weakened immune system.

Here are some foods that can become easily tainted with bacteria, such as listeria (causing the infection called listeriosis), E. coli, Salmonella, Campylobacter, and Vibrio, in addition to Toxoplasma, a parasite.  Are some of these foods surprising to you?

  • Cold hot dogs or deli lunch meat (cold cuts)—always cook or reheat until the food is steaming hot
  • Dry-cured, uncooked salami
  • Unpasteurized (raw) milk and milk products, including raw milk yogurt
  • Soft cheeses made from unpasteurized milk, such as blue-veined (a type of blue cheese), Brie, Camembert, feta, goat cheese, and queso fresco or blanco
  • Cold smoked fish
  • Deli-prepared salads with egg, ham, chicken, or seafood
  • Refrigerated pâté
  • Unwashed fresh fruit and vegetables
  • Unpasteurized fruit juice or cider
  • Raw sprouts, such as alfalfa sprouts
  • Raw or undercooked beef, especially ground beef, or other raw or undercooked meat and poultry
  • Raw or undercooked shellfish (such as oysters)—these items may carry the hepatitis A virus and should be cooked thoroughly to destroy the virus
  • Some types of fish, raw or cooked, as it may contain high levels of mercury
  • Sushi and sashimi, which often contain raw fish—commercially frozen fish (especially those labeled “sushi-grade” or “sashimi grade”) is safer than other fish, but check with your doctor before eating these foods
  • Undercooked eggs, such as soft boiled, over-easy, and poached; raw unpasteurized eggs, or foods made with raw egg, such as homemade raw cookie dough

Symptoms of foodborne illnesses differ depending on the pathogen or bug that causes the illness. FOODSAFE instructors warn that if you’ve ever had what you called the “24-hour flu” – you likely had food poisoning instead. Symptoms include:

  • diarrhea
  • stomach pain or cramps
  • nausea
  • vomiting
  • fever

Sometimes a headache and muscle pains also are present. E. coli usually does not cause a fever, and diarrhea often is bloody. The time when symptoms begin can vary widely, from a few hours to 10 days after eating the tainted food, or even later. With listeria, symptoms may not start until a few weeks later.

But with most foodborne illnesses, people start feeling sick in the first day or two after infection.

Have you ever had food poisoning?

  1. Great information that you have give. Actually we need to take care of food. If we don’t it can cause to a lot of problems. This web site is some thing different that give you a great information then any other sites.


  2. “..Proper cooking can destroy bacteria, but they can grow even on cooked food if left out too long…”

    I took a “Food Safe” course recently that reinforced the importance of this fact. Ever since, this has made those buffet brunches really unattractive for me! The average consumer just has no idea if that creme caramel or bacon quiche or sliced ham has been cooked properly and then stored/refrigerated properly afterwards.

    And those deli cabinets – wow! Those pre-sliced meats provide all that open surface for bacteria to thrive on.The listeriosis outbreak in Ontario was apparently started because of lack of correct cleaning of the cold cuts slicing machines.

    Much better to roast your own chicken and cut your own slices for sandwiches.



  3. Ever since the Maple Leaf factory poisoning tragedies, I’ve been shocked to see people still lined up in the deli buying processed meats.

    Don’t they get it? The potential for bacterial contamination, either in the factory or in the deli display, is huge. I picture all of that processed meats now as having a purplish sheen all over each limp slice. Yuck……. It’s just not worth the momentary enjoyment of having that baloney sandwich. 😉

    I’m forwarding this to my family and to my friends along with a reminder NOT to put this highly processed junk into our bodies.

    Thank you for this.


  4. Thanks for this – good info.

    It’s hard to find useful information these days. Every site you go to is just copy-posting the same old content.

    It’s refreshing to hear something different, no matter the topic.

    Anyways, thank you!
