You're Most Likely to Get Food Poisoned at a Restaurant

Each year, nearly 50 million Americans fall ill from contaminated food, according to the National Institute of Health (NIH). Harmful bacteria are the most common cause of foodborne illness. Symptoms can range from mild irritation to severe reactions, including stomach cramps, vomiting, diarrhea, fever, and dehydration.

Americans love to eat out, preferably several times a week, according to the Nation's Restaurant News, a publication for the restaurant industry. At the same time, there is growing concern that restaurant food may not be as healthy as it should be. On top of worries over portion sizes and excessive fat, salt and sugar content -- all believed to contribute to weight problems -- a new study by the Center for Science in the Public Interest (CSPI) warns consumers about the heightened risk of food poisoning from restaurant fare.

Each year, nearly 50 million Americans fall ill from contaminated food, according to the National Institute of Health (NIH). Harmful bacteria are the most common cause of foodborne illness. Symptoms can range from mild irritation to severe reactions, including stomach cramps, vomiting, diarrhea, fever, and dehydration.

Between 2002 and 2011, more than 1600 outbreaks of food poisoning, affecting over 28,000 people, were connected to restaurant visits, based on the CSPI study. By contrast, only about 13,000 people became victims of such ills originating in their homes.

Unfortunately, the numbers are vague because not all outbreaks are reported, nor are their causes always clearly identified. Reporting has decreased by 42 per cent, the researchers say, not necessarily because there are fewer cases but rather because of budget cuts for public health investigations.

Besides restaurants and private homes, food poisoning can take place just about anywhere, including in the workplace, at catered events, in schools, and at picnics. Most vulnerable among the afflicted are children and the elderly.

To prevent foodborne illness, experts recommend a number of precautions. Especially animal food products are susceptible to spoilage if not stored properly. You want to make sure items like meat, fish, eggs, and dairy foods are fully cooked or pasteurized before they are eaten. Raw meat or fish (e.g. steak tartar, sushi) may be fashionable, but the potential health threats are significant. If you love uncooked animal foods, be sure to patronize only reputable establishments.

Raw vegetables can also spoil and wreak havoc on your digestive system. Uncooked plant foods should always be thoroughly washed and stored in the refrigerator until consumption.

Dairy products like cheese and yogurt should always be kept refrigerated. Some types of cheese have bacteria and molds that add to their flavour and character. Hard varieties typically last longer than soft ones, but all require appropriate storage and should not be left exposed to warm temperatures for extended periods of time.

Preventive measures must also include proper cooking techniques and personal hygiene. Washing hands before and after touching food is imperative, especially when it involves uncooked animal foods like meat, poultry, and seafood.

Of course, when you eat out, you are at the mercy of those manning the kitchen. The only advice one can give is that if you have encountered problems in the past, you may not want to go back for seconds. On the other hand, if you are a regular at a particular eatery and you trust the place, you may want to stick with it. Of course, that is still not a foolproof strategy. All you can really do is minimize the risk by using your best judgment.

Kinds Of Food Poisoning You Should Know About (And Avoid)
Campylobacter Enteritis(01 of08)
Open Image Modal
A common bacterial infection producing severe gastrointestinal upset that can hang around as long as two weeks. It's rarely fatal in healthy people.The culprits: Improperly slaughtered or processed meat not thoroughly cooked, contaminated vegetables, milk or water. Pets can also shed the bacteria through their "business."What it feels like: You'd pay closer attention to the flulike symptoms (fever, aches and pains) if you weren't running to the bathroom every 15 minutes of your life.Maybe you shouldn't have: Plucked that mass-processed pack of pork chops out of the "manager's special" bin. Also, if you really need to be told, leave seagulls alone. They're neither friendly nor tasty and are known to harbor higher concentrations of the bacteria. Common sense and decent kitchen cleanliness should protect you from needless downfall. Related: Are These 5 Foods Trying To Kill You?Photo via Flickr user StuartWebster (credit:Flickr: StuartWebster)
Cholera(02 of08)
Open Image Modal
Contrary to what literature might have you believe, there will be no love in the time of cholera, only misery, woe and lots of diarrhea.The culprits: Contaminated water and eating raw or undercooked seafood that was hanging out in that water.What it feels like: Being slowly dried in a dehydrator that looks surprisingly like your bathroom while your abdomen is squeezed by a giant godlike fist. You might just want to set up shop in there for a spell, the toxin in the cholera bacteria causes any water in your body to "release." Replenish as you might, it likely won't stay in there very long. Keep at it diligently, though, and you'll be fine in about a week.Maybe you shouldn't have: Splashed around in a stagnant portion of the Meekong Delta for so long, or eaten those Mexican oysters with quite as much gusto.Photo via Flickr user philosophygeek (credit:Flickr: philosophygeek)
E. Coli Enteritis(03 of08)
Open Image Modal
The black sheep of the food poisoning world, E. coli's the one with a strain that'll actually kill you regardless of treatment attempts. How subversive.The culprits: Escherichia coli, or E. for short, has one incredibly powerful strain: O157:H7, although other related strains can cause infection as well. This bacterium is found in mass-processed ground beef and on vegetables that were improperly cleaned or handled by contaminated fingers. What it feels like: You've been stabbed in the colon, which would explain the crippling cramps and other things that might happen if one were actually stabbed in the colon, including blood. Not that there's a "better" food poisoning to get, but this is one you really want to avoid.Maybe you shouldn't have: Eaten that rare burger of questionable origin while chugging raw milk in that crazy crowded public pool, all of which have been known to harbor the bacteria.

Ciguatera (Fish Poisoning)(04 of08)
Open Image Modal
An incurable disease caused by eating fish contaminated by coral algae toxins. A real doozy, with an estimated 50,000 cases each year. The culprits: Ciguatera is limited to fish of tropical origin. It's impossible to detect by seafood processors, and can't be killed by cooking or freezing. Live in fear of grouper, or continue on with your life with relatively minimal risk.What it feels like: At first, typical food poisoning symptoms may present, but the bigger problem with ciguatera is its severe and often irreversible neurological effects. These can include trouble sensing hot or cold, tingling "phantom limb" pain in the extremities and other symptoms that may be confused with anything from multiple sclerosis to heart failure. Maybe you shouldn't have: Hit that fried "mystery tropical fish" eating contest at that Margaritaville in that tropical location with your buddies. To minimize your risk of catching this seriously unfun bug, make sure you know what your fish is and if possible, where it came from. Larger fish from shallower waters in a tropical environment are your worst bet. Related: Trouble Brewing For The FDA. And, Sushi.

Listeria(05 of08)
Open Image Modal
The range of listeria infection, or listeriosis, lands you somewhere between asymptomatic and dead and can occur from eating or drinking basically anything that was grown, raised or milked.The culprits: Raw or improperly pasteurized dairy products, vegetables grown in contaminated soil (yup, it can live in soil), preserved and smoked meats (can be identified by a slippery or slimy film), canned and raw seafood and fresh fruit. What it feels like: A bad flu, although more serious complications like meningitis can occur in people with weakened immune systems, as well as in young children, pregnant women and the elderly. Maybe you shouldn't have: Eaten all those root vegetables straight from the ground without washing them right after milking your cow. I mean a hippie farmer's life is great, unless your land is rife with listeria. Photo via Flickr user bucklava (credit:Flickr: bucklava)
Staphylococcus(06 of08)
Open Image Modal
This is the picnic food poisoning everyone warns you about, especially you, dude who brought the mayo-choked potato salad (try this one instead). The culprits: The bacteria releases its toxins at the comfy incubator that is room temperature food, which gives staph food poisoning its signature cookout-ruining reputation. The worst part? Reheating contaminated food won't kill it off. Actually the worst part is the symptoms.What it feels like: Explosive, and not in a romantic feelings kind of way. Within an hour of ingesting contaminated food, both ends will be entirely occupied for up to a day. The good news is, once it's out, it's out and you can get right back to the picnic. Oh wait, it's over. Maybe you shouldn't have: Microwaved that leftover potato salad thinking no bug could possibly survive the ordeal.Photo via Flickr user stu_spivack (credit:Flickr: stu_spivack)
Salmonella(07 of08)
Open Image Modal
The bacteria that causes salmonellosis, or salmonella poisoning, has a serious reputation among poultry and their handlers, and BOY does it love hanging out on the stretches of counter you missed with the sanitizer.The culprits: Although eggs, processed chicken parts and other raw meat are particularly good at spreading the bacteria, pet reptiles and rodents are also carriers. Wash everything any dead or live animal comes in contact with and maybe don't allow live animals in the kitchen while you're cooking, period.What it feels like: Your small intestine betraying you entirely. Expect a week or so of your typical diarrhea, abdominal cramps and possibly a fever.Maybe you shouldn't have: Attempted your own Japanese-style chicken breast sashimi or let Shelly the turtle roam around willy-nilly on the cutting board. Especially before slicing said chicken sashimi.Photo via Flickr user Casper Jen (credit:Flickr: Casper Jen)
Shigellosis(08 of08)
Open Image Modal
Similar to salmonella but yet so very different is shigella, which attacks the large intestine rather than the small. The culprit: You're going to love this -- human waste. While plenty of food-borne illness can be spread this way, particularly by catching a ride in food or water, many cases of shigellosis can be directly attributed to contact with... well, you know. It can also be resistant to antibiotics, so definitely practice safe sewage-wading.What it feels like: Salmonella, only with more blood.Maybe you shouldn't have: Taken on that blackout drunken dare to see what's really under that manhole by the creek, then gone straight to In-N Out. Just maybe. We live in a developed nation, you almost have to try to get this one. It's Darwinism, people.Photo via Flickr user Nathan Reading (credit:Flickr: Nathan Reading)
