How Do You Know If You Have Food Poisoning?

November 10, 2019


[ ♪ Intro ] Most of us have experienced food poisoning… You know it’s like the vomiting and the
diarrhea. The gastrointestinal torment that can leave
you huddled miserably on the bathroom floor. But food poisoning, or foodborne illness,
isn’t just one thing. In fact, the U.S. Centers for Disease Control
names 31 unique species of bacteria, viruses, and parasites as common culprits, but there
are hundreds in total. And different microbes tend to contaminate
different foods, cause slightly different symptoms, and have different incubation periods:
the time between when you get infected and when you start feeling bad. So figuring out if you have food poisoning
and where you got it can be trickier than you might think. The number one cause of food poisoning in
the U.S. is norovirus, which causes around half the cases, according to the CDC. Viruses are minimalist microbes. They’re basically some genetic material
with a protein coat. So they can’t reproduce or do much on their
own at all, they need a host cell. And when you eat a norovirus-contaminated
salad, it finds plenty of hosts in your gut. When the virus finds an intestinal cell, it
tricks membrane receptors to get inside, and then hijacks the cell’s machinery to make
copies of itself. Eventually, those virus minions burst from
the infected cell to find more victims. And at the same time, your dead and damaged
cells release chemicals that trigger an inflammatory response in your body. Nearby blood vessels dilate and leak plasma
into the infected tissues, which kicks off the fight against the invaders. And more chemical signals are released to
attract specialized immune cells. This inflammatory response in your gut contributes
to some of the classic symptoms of food poisoning: diarrhea, vomiting, and sometimes a low fever. So just know that when you’re puking your
guts out, at least that’s your own immune system kicking some microbe butt. It’s been difficult to study norovirus because,
until recently, researchers haven’t been able to grow intestinal cell lines in the lab that it can infect and survive in. Before that, heroes among us have volunteered
to be infected with norovirus so scientists could better understand it. Now, they’re even testing a norovirus vaccine in humans! But even though norovirus is the leading cause
of food poisoning in the U.S., most cases of norovirus aren’t from food. It’s highly contagious, so infected people
or contaminated surfaces can spread it too. And it’s commonly called a stomach bug or
stomach flu, even though norovirus isn’t related to the influenza virus. So how do you know if you should blame your
Uncle Carl’s fruit salad for your upset stomach? Well, that takes some detective work. The simplest way is to try finding the source: did any other people who ate the fruit get sick around the same time you did? Or did you start puking after hanging out
with your buddy’s preschooler, who was a little under the weather? That’s basically how state health agencies
and the CDC approach food poisoning outbreaks too, just on a bigger scale. They have to try trace the source, so they
can stop the spread of a microbe. These agencies monitor reports of illness
from hospitals to look for weird spikes or clusters of foodborne illness. They’ll do DNA and RNA tests and perform
other analyses on poop samples from patients to determine what microbe they’re dealing with, from norovirus, to bacterial baddies you may recognize like Listeria, E. coli, and Salmonella. Then, they’ll interview patients to generate
and test hypotheses about where it came from. Like, if most of those patients ate the same
brand of alfalfa sprouts, they’d go swab that produce packaging facility to look for the microbe. When they do find the source, they try to
stop its spread. The state health agency may shut down a restaurant,
or the Food and Drug Administration may recall a product. But, obviously, it’s kind of hard for you
to do that level of investigation while you’re suffering by a toilet. It’s not like everyone can just run a molecular
analysis for norovirus. The good news is, for most healthy folks who
aren’t babies or old, food poisoning is a sucky illness, but you’ll get better on
your own. So it’s not super important to know what
kind of sick you are. The only way to really know what’s ailing
you is to go to a medical professional. Which is also advisable if you don’t get
better in a few days or if you get severely dehydrated from all that vomiting and diarrhea. So, like, if you’re worried, go to them
instead of watching me on youtube. I’m not a doctor. And you can be careful about what you eat
to try and avoid food poisoning altogether. Pay attention to those recalls on local news, and wash your hands so you don’t spread any nasty microbes! And if you’re preparing fruits and veggies
to eat raw, make sure you wash them. A thorough scrub is important even if you
don’t plan to eat the outside, because, for instance, cutting into a melon can transfer
microbes from the outer surface to that juicy middle. The FDA also recommends removing any bruised
or damaged parts, and the outermost leaves of lettuce or cabbage. Plus, thoroughly cook your food, especially
beef, poultry, and eggs. Because heat kills any bacteria that might
be on them. So next time your friend or family member
is taken down by food poisoning, you can share your fun facts with them… I’m sure they’ll be thrilled! But, seriously, if you want to learn more

    Fortunately (or unfortunately), I can usually tell what caused it when it's something I ate. I'll start to feel sick, burp, and all it'll smell like is rotten eggs mixed with whatever caused it. Doesn't matter if I had anything in between or not.

    I have testing at school and they gave us breakfast. I was REALLY hungry so I ate the breakfast bar and drank the juice which tasted a little funny but I didn’t think much of it. Fast forward to 2 hours later when that section of the test is over I start to feel nauseous but I didn’t throw up. Then once a I got home and took a nap I woke up suddenly and threw up my dinner all over the floor. I threw up the tea that my brother made me to feel better. Ever since yesterday I’ve been throwing up everything I ate. I have no idea if it’s food poisoning or not. Do any of you know what’s happening to me? (Sorry it’s so long)

    My food poisoning started out as my indigestion smelling eggy which is weird because I don't normal burp. I felt fine then a few hours later everything happened.
    I was ill for a few days.
    Think it was from Pumpkin seeds.
    Edit. I also had my period at the time and 2 days in to quitting cold turkey from cigarette.
    I lost weight n looked great afterwards tbh.

    I got a food poisoning this morning around 1:00 AM I had diarrhea first but I didn’t think much of it. Then I woke up with a horrible pain in my stomach. It wouldn’t go away until 6:00 PM! Then I started vomiting and my throat was swelling up, it was hard to breath. I don’t know what caused it because I haven’t been discovered with any food allergies yet.

I knew it was bad the next morning when I had to use the bathroom, then two more people and myself again. Had breakfast and round three in the bathroom before WORK. Two hours and four more rounds before my boss came to check me and let me go home. She didn't believe me because I had a hangover as well.

In fact, after 3 days I have only had abdominal cramps but I couldn’t eat anything but ginger ale and crackers for a while. I was worried how long it would take me to get over whatever I have, if it is food poisoning. So far I’ve been sick for 3 days.
