Not all cases of food poisoning are that serious, but they can still cost you a day or two of downtime and you may not even be aware of the fact it’s your food that has incapacitated you. Other cases can land you in the hospital and even be life-threatening.

With the current heatwave surging across the US, we thought we’d identify some of the common culprits, and you may be surprised by what can and often does make you ill, both in restaurants and at home.

1. Rice

Without a doubt, one of the most common causes of food poisoning is from rice, referred to as “fried rice syndrome” and it’s one most people are blithely unaware of. Rice contains Bacillus cereus, a toxin-producing bacteria that is one of the most common causes of food poisoning. How common are incidents?

An estimated 63,000 cases of food poisoning caused by B. cereus occur each year within the U.S., according to a 2019 article published in the journal Frontiers in Microbiology. Most cases however aren’t even reported, as the symptoms are usually mild enough to avoid a doctor’s visit, but uncomfortable enough to make you take the day off work.

How does it make you sick?

Leftover fried rice is a primary culprit, B. cereus occurs naturally on rice and no, you cant wash it off. You also can’t cook it to death. The bacteria release two types of toxins that each cause a different illness — one causes diarrhea while the other toxin elicits vomiting, according to the U.S. Food and Drug Administration (FDA) Bad Bug Book.

After you’ve cooked your rice, it’s usually left to stand at room temperature and then reheated later. Its this “resting phase” at room temperature that allows the bacteria to produce the toxins. Reheating will destroy the bacteria, but doesn’t kill off the toxins. The longer the rice is left standing around, the more toxins are likely to form.

The first type of toxin is released in the small intestine after the bacteria are ingested, and causes diarrhea, cramps, and occasionally nausea but rarely vomiting. Symptoms typically begin 6 to 15 hours after eating contaminated foods, which can include various meats, milk, vegetables, or fish. The symptoms typically subside after about a day.

The second type of toxin is released by the bacteria in the food before it’s consumed. Starchy foods, such as rice, are the most common sources of food affected. The toxin causes vomiting and nausea within 30 minutes to 6 hours after eating the contaminated food. Symptoms subside after about 24 hours.

Staying Safe with Rice

Keep your leftover rice at about twenty degrees above room temperature, or if you’re cooking to eat later, ensure it stays hot. This will help reduce the bacteria’s ability to produce toxins. If you’ve got rice that’s been standing out for a few hours or overnight, throw it away and cook a clean batch. 

Rice purchased from takeaway shops should never be “put away” for later consumption.

2. Chicken

One of our favorite foods and also a food with the potential to wreak havoc in your kitchen if not handled properly. It’s the raw meat and undercooked chicken that pose the most risk, particularly cross-contamination of cutting boards, working surfaces, storage areas, and knives.

Research from the UK, US, and Ireland found that 41–84% of raw chicken sold in supermarkets was contaminated with Campylobacter bacteria and 4–5% was contaminated with Salmonella. Sorry folks, but turkey and duck don’t perform any better.

Salmonella and Campylobacter are the most common pathogens found on raw chicken. Some other pathogens include:

• Staphylococcus aureus
• E. coli
• Enterococcus
• Klebsiella

How does it make you sick?

If you accidentally consume raw or undercooked chicken or contaminate other work surfaces, knives, or foodstuffs, the most common symptoms that occur from eating chicken that contains one or more of these pathogens are:

• abdominal cramps
• diarrhea
• nausea
• vomiting
• fever
• headache
• muscle pain

Approximately 1 in 1,000 reported cases of Campylobacter infection result in Guillain-Barré syndrome, according to the Centers for Disease Control and Prevention.

In cases where Salmonella is involved, the diarrhea is usually very liquid. With Campylobacter, it’s often bloody. Symptoms usually occur within one to two days after consuming Salmonella and within 2 to 10 days after consuming Campylobacter. Symptoms usually go away after around four days. In severe cases of Campylobacter infection, antibiotics may be needed.

Staying Safe with Chicken

Always store your chicken in separate airtight plastic bags or containers, away from other meats and foodstuffs. Wash all utensils, boards, and surfaces that have been in contact with raw chicken before using them for other foodstuffs. This includes your hands. Ideally use a separate cutting board for chicken.

• Use a meat thermometer to ensure the chicken has reached an internal temperature of 165°F (74°C).
• Send back any chicken meal you order that you suspect is undercooked.
• Avoid eating any trendy dishes that contain raw chicken. 
• Place uneaten chicken into the refrigerator with an hour of letting it cool, particularly if the weather is sweltering. 
• Avoid ordering dishes like chicken pie from food outlets that have a slow turnover in product, particularly in summer.
• If chicken smells even remotely suspect while you’re preparing it, return it to the store or feed it to Fido. If the raw chicken disintegrates easily (smears), that is another sign of spoilt meat.

Thorough cooking will destroy all the pathogens chicken may carry, but with items like salads and other lightly cooked foods, you risk contracting the pathogens through cross-contamination. 

3. Shellfish

We’re going to focus on crayfish, lobsters, crabs, mussels, and yes, even shrimp, rather than traditional fish. The reason will soon become apparent. Although traditional fish can result in scombroid poisoning, the most dangerous and fatal cases of food poisoning belong to the crustacean clan.

People who suffer from any form of allergic reaction need to be particularly cautious when eating shellfish. Allergic reactions can be sudden, dramatic, and life-threatening, often resulting in anaphylaxis (constriction of the throat and an inability to breathe). Seek immediate medical care if you suspect shellfish poisoning.

Always ensure someone who tends to react easily to allergens has an EpiPen close to hand when sampling shellfish.

In shellfish poisoning, the poisonous ingredients are toxins made by algae-like organisms called dinoflagellates, which build up in some types of seafood. There are many different types of shellfish poisoning. The most well-known types are paralytic shellfish poisoning, neurotoxic shellfish poisoning, and amnesic shellfish poisoning.

• Paralytic shellfish poisoning: About 30 minutes after eating contaminated seafood, you may have numbness or tingling in your mouth. This sensation may spread down to your arms and legs. You may become very dizzy, have a headache, and, in some cases, your arms and legs may become temporarily paralyzed. Some people may also have nausea, vomiting, and diarrhea, although these symptoms are much less common.
• Neurotoxic shellfish poisoning: After eating contaminated clams or mussels, you will most likely experience nausea, vomiting, and diarrhea. These symptoms will be followed soon after by strange sensations that may include numbness or tingling in your mouth, headache, dizziness, and hot and cold temperature reversal.
• Amnesic shellfish poisoning: This is a strange and rare form of poisoning that begins with nausea, vomiting, and diarrhea. These symptoms are followed by short-term memory loss and other less common nervous system symptoms.

Staying safe with Shellfish

You can still safely enjoy shellfish by following a few simple precautions. Never buy shellfish from fish markets or local vendors if there is a red tide in the area. Always ensure produce is fresh and if the product is dead, ensure it is packed in ice and does not smell overly “fishy”.

• Store live clams, oysters, mussels, crabs, lobsters, and crayfish in a refrigerator as soon as possible, in well-ventilated containers, and cover with a damp cloth or paper towel. Place container in a second bowl filled with ice and store on the bottom shelf of the refrigerator.
• Avoid buying clams, mussels, and oysters during the summer months. Hold on to your recipes till winter.
• Avoid packages of frozen seafood containing ice crystals. This is a sign the seafood has previously thawed and been re-frozen.
• Pick up seafood toward the end of your shopping trip and ask to have it bagged separately from other groceries.

When preparing your dish, follow these simple rules;

• Keep raw and cooked seafood separate to avoid cross-contamination.
• Use two separate cutting boards, one for raw seafood and the other for cooked seafood.
• Thoroughly wash your hands, utensils, plates, and cutting boards that have touched raw seafood.
• Defrost frozen seafood in the refrigerator, under cold running water, or in the microwave. Never defrost seafood on the counter.

When cooking live mussels, clams or oysters, discard any shells that do not open during cooking. Pregnant individuals, older people, young children, and people with weakened immune systems should avoid raw shellfish (oysters, clams, scallops, mussels, or ceviche)

Finally, a note on the physiology of shellfish. They don’t have lungs and obtain oxygen by having seawater filter over their flesh. Contaminants and pollutants are far more likely to seep into their flesh than with normal free-ranging fish that use gills. 

Yummy, definitely, but as to the toxins and environmental pollutants contained in the flesh of shellfish, we’d rather stick to traditional fish.

4. Vegetables and leafy greens

Finally, a reason not to eat your greens. Although you may not think it, vegetables, particularly raw vegetables, are one of the most frequent causes of food poisoning. In fact, fruits and vegetables have caused a number of food poisoning outbreaks, particularly lettuce, spinach, cabbage, celery, and tomatoes.

Between 1973 and 2012, 85% of the food poisoning outbreaks in the US that were caused by leafy greens such as cabbage, kale, lettuce, and spinach were traced back to food prepared in a restaurant or catering facility. 

How do they make you sick?

Vegetables and leafy greens can become contaminated with harmful bacteria, such as E. coli, Salmonella and Listeria. This can occur across various stages of the supply chain. Contamination can occur from unclean water and dirty runoff, which can leach into the soil that fruits and vegetables are grown in or dirty processing equipment and unhygienic food preparation practices can cause contamination. 

Leafy greens are especially risky because we love eating them raw.

Staying safe with your greens

By practicing a little common sense you can still safely consume your greens (sorry kids) without risking food poisoning.

• Don’t buy salad mixes in packs where any of the product appears brown or spoilt.
• Wash thoroughly and then, just to be on the safe side, give it another rinse off. Lettuce and similar leafy vegetables can benefit from a spinner to remove any impurities and the occasional wormy passenger.
• Ensure you prepare your raw vegetable dishes well away from any raw meat or fish.
• When dining out, reconsider that Ceasar salad. Cooked food in public areas is always far safer than raw food.
• Buffets with pre-prepared salads that have been left to stand out for a period of time should also be avoided.

5. The humble Egg

One of our favorite foods, we use eggs to bake, to coat, to fry to poach, to scramble and they’re often found as an accompaniment in dishes. Cooked, particularly well-cooked eggs don’t pose a problem. It’s raw or undercooked eggs that can lead to food poisoning and occasionally, even death.

How do eggs make you sick?

It’s our old friend Salmonella, once again. Eggs can carry Salmonella bacteria, which can contaminate both the eggshell and the inside of the egg. In the 1970s and 1980s, contaminated eggs were a major source of Salmonella poisoning in the US, but since 1990, improvements have been made in egg processing and production, which has led to fewer Salmonella outbreaks.

Despite improvements in production, each year Salmonella-contaminated eggs cause about 79,000 cases of food poisoning and 30 deaths, according to the US Food and Drug Administration (FDA).

Staying safe with eggs

Avoid buying dirty eggs. That’s always a clear sign of possible contamination with Salmonella. Clean eggs aren’t a guarantee, but you’re far safer and ideally look for pasteurized eggs.

If you are going to eat your eggs raw, you should only ever purchase pasteurized eggs.

Always ensure your eggs are well cooked at a high temperature. If you tend to like your eggs runny then you’re potentially leaving a window open for the Salmonella. Again, consider rather purchasing pasteurized eggs.

Free-range eggs are often a far healthier alternative to caged eggs, but remember to wash off the eggs thoroughly and cook properly.

Two Texas residents, who reside in long-term care facilities, contracted Listeriosis. The infections were traced back to contaminated chicken products from Tyson Food Inc, prompting a Food Safety Alert.

Listeria monocytogenes is a bacteria found in soil and water. Cattle and poultry can carry the bacteria, which causes a severe type of food poisoning in humans. Listeria accounts for only 1 percent of reported bacterial food-borne infections, but these cases can be fatal when not treated with appropriate antibiotics.

The CDC reports approximately 1,600 people contract Listeriosis each year in the United States, leading to 260 deaths.

The US Department of Agriculture Food Safety and Inspection Service compared samples from Tyson Food Inc with those of the infected Texas patients. The bacterial strains from the two patients were a match indicating a shared original source.

Public health agencies traced their exposure to chicken products stating “two precooked chicken samples from two establishments that are closely related genetically to Listeria monocytogenes from ill people.”

Listeriosis was found in fully cooked chicken products marketed under brands such as Tyson, Jet’s Pizza, Casey’s General Store, Marco’s Pizza, and Little Caesars.

The CDC and public health agencies can respond quickly to listeriosis outbreaks because of the Whole Genome Sequencing Project. This early detection tool helps identify infectious disease public health threats before they can spread. When someone tests positive for Listeriosis, scientists genetically sequence the entire strain of bacteria. When two patients test positive for the same strain, public health officials can search for the source causing the infections. According to the CDC, the Whole Genome Sequencing Project allows scientists to:

• Detect early clusters of Listeria infections
• Link cases of Listeria to a likely source
• Identify unrecognized sources of Listeria
• Stop Listeria outbreaks while they are still small

Listeriosis is a potentially life-threatening infection when people eat food contaminated by the bacteria Listeria monocytogenes. Most people who contract Listeriosis have a mild illness, but those with suppressed immune systems or over age 65 can become very sick.

Patients with autoimmune diseases, HIV, cancer, or transplants are at increased risk. The infection can spread to the bloodstream causing sepsis or to the brain, causing meningitis or encephalitis.

The symptoms of Listeria can arise days to weeks after exposure. Common symptoms are similar to the flu, including fever, chills, muscle aches, and diarrhea. Some may develop more concerning symptoms such as headaches, a stiff neck, or confusion.

Listeriosis is especially concerning during pregnancy. Pregnant women are at a much higher risk of getting sick from Listeriosis. Pregnant women who contract Listeriosis generally have a mild illness, but the disease has been linked to miscarriage, stillbirth, and preterm labor.

Listeriosis can be transmitted from a pregnant woman to her baby through the placenta. The placenta is the organ inside the uterus that keeps the baby alive. Maternal blood circulates through this internal filtration system. The growing baby receives oxygen and nutrients from the mother, and the placenta removes carbon dioxide and waste products. 

The placenta is also the defense system against invading infections like bacteria and viruses. Placental immune system cells called trophoblasts are the first line of defense against any invading organisms.

Most infectious invaders do not make it across the placental defense system. Trophoblasts stop them in their tracks. Listeriosis can cross the placental barrier leading to infections in the baby.

Listeriosis can cause intellectual disability, paralysis, seizures, and blindness. Infected babies may develop problems in the brain, kidneys, and heart.

The CDC Food Safety Alert linked this listeria outbreak to fully cooked chicken supplied by Tyson Food Inc recalling products “shipped nationwide to retailers and institutions including hospitals, nursing facilities, restaurants, schools and Department of Defense locations.”The products affected include:

• Fully cooked chicken strips
• Diced chicken,
• Chicken wing sections
• Fully cooked pizza with chicken.

The US Food and Drug Administration offers this helpful video to help families learn about preventing foodborne illnesses.
