The Food Poisoning Lurking In Your Freezer

[@CattyTomfoolery]

I honestly don't understand why this channel doesn't have more subs. It's absolutely fascinating and educational. Love this channel.

[@Barnardrab]

Great content like this is drowned in the sea of KZbin channels. I never heard of this channel until Ana did a collaboration video with either Physics Girl or Braincraft (It was one of the two, I don't remember which.

[@Saffrone221]

Theres millions of videos that focus on games, sex, easy money ploys, and tv crap. This is an awesome show hidden in thousands of other educational videos.

[@greenbeevideo765]

That microscope footage was amazing!

[@MUtley-rf8vg]

I thought the rocket listeria doodle was a bit of an over personified version of the reality, but they really look like little rockets in the video! Amazing and scary.

[@sapphiresapphic]

oh lord any of your vids about disease or parasites always make me paranoid

[@Jabrils]

This is both scary & awesome, either way thanks Anna!

[@HaniaHeartHands]

I once had food poisoning and if I had to describe it...it is TERRIBLE!!! I was around seven or eight at the time and I got a salad for a dollar off at a store. I went home ate it and went to bed. In the middle of the night I woke up and started crying in pain. Next I started puking . So how it feels is like someone is grabbing your insides and twisting them up into a knot, and you can't stop puking seriously like non stop and when you have nothing to puke up then it just hurts as heck because your body won't stop trying to puke. In summary I EFFIN HATE IT

[@TheMrRiceFighter]

meh. Bacon increases My risk of cancer. Swimming increases my chances of drowning. meh. thanks for the info, but won't stop me from eating these frozen nuggets.

[@powderedbread2905]

Nathan V rest in peace

[@thesciencetwins7707]

[@Myokuju]

Im new to your channel and it has absolutely gotten me hooked. You have excited the science geek inside

[@1Rekuiem]

You just love ruining things don't you D: Now I can't eat between this and wasps in my figs! I actually had a freezer product I enjoy recalled several months ago due to listeria! I fortunately threw the product out!

[@grossscienceshow]

Ooh, thank goodness!

[@MUtley-rf8vg]

After the fig video I went and bought myself a bunch of figs and devoured the whole basket by myself. Because nature is awesome.

[@eiserntorsphantomoftheoper2154]

I bet you had wonderful afternoon.

[@MUtley-rf8vg]

+LagiNaLangAko23 Come again? I just like figs. Not........incest.

[@lydiaherondale3679]

although listeria isn't usually found in food's because of pasteurisation laws (where I live in the UK anyway) it can be found in soil. My nan was the first person to die in our area from the bacteria after 20 years. Unfortunately, the test results for the bacteria came too late, and if she would've survived she would have severe brain damage from other complications. Thankfully she passed in a matter of days in an induced coma after the effects became known.

[@pyromaniac404]

Lydia Herondale oh wow, I had no idea it could be found in the soil!! I'm so sorry about your nan though :(

[@indiciaobscure]

This bacteria has evolved through all the stages on Plague Inc.

[@TheMelvinWei]

How come some people don't get food poisoning ever, like me, and others seem very susceptible? It is just due to partiality for raw(er) meat, oysters, and unsterile technique when eating or is it mostly based on how strong your digestive system & immune system are?

[@peterschubert3429]

Really like the initiative to spread food safety knowledge :) Two points I'd like to add - you left out the immunocompromised (such as cancer and HIV-patients) out of the risk group. YOPI - young, old, pregnant and immunocompromised is the term normally used in scientific literature. :) Listeria uses host proteins to move around as correctly described but also loses its Flagella at body temperature in order to save energy.

[@adtc]

Why do people eat rare beef steak? If the meat is to be thoroughly cooked? Is there a way to cook the meat thoroughly and still have the rare appearance?

[@miloradvlaovic]

You can deep fry it, fume-roast or even pour some vinegar on the (over)cooked meat. The result will be more juicy and more chewy meat reminding thus of the raw steak for example. Why do people eat it raw? It's most likely one of many of the cockamamie cooking trends

[@peterschubert3429]

sous-vide cooking often does the trick!

[@erdvilla]

Is there any food-related disease that can kill a teenage in less than 18 hours from symptoms onset? I ask because over 30 years ago one of my neighbors got home from school feeling sick after eating a sandwich at school, she died the next morning. So I don't know if it was food poisoning or if she was accidentally or intentionally murdered with actual poison (accidentally if the food was stored near poison, or intentionally if someone poisoned her with a high enough dose to kill her so fast). I don't know the exact symptoms she had because her mom doesn't like talking about of course. But it was legally ruled "Food poisoning".

[@brandonkelley6500]

There are a few pathogens that can cause death in a quick amount of time.. some pathogens cause straight up organ failure, other pathogens can cause sepsis or septic shock... Can't think of the specifics right now... But I think the usual food borne pathogens like e. Coli, listeria, salmonella , fungus, etc generally don't cause near immediate death. . . Although some pathogens can cause near immediate symptoms

[@makraiz]

More scary than gross I think, but still an awesome video.

[@kathybones8552]

Since Listeria grows so slowly, it takes a while for companies to learn that they are breeding it, and distributing it to consumers!! Food product quality control doesn't catch Listeria for a little while.

[@linushyper300]

I love that little twitch you're doing with you're saying "Gross Science" ♥

[@KauanRMKlein]

How is this diagnosed? Seeing that the disease can infect lots of different organs and even different systems, how do doctors get to say "oh, it's lysteriosis" before the autopsy?

[@mix7506]

don't let its small size fool you (insert Lenny face here)

[@Azrielfiend]

Oh, that size

[@MusiCaninesTheMusicalDogs]

LoL at the end! 😂

[@watrudoininmehchanelstopre5497]

why am i still watching these?

[@music4dance837]

Dang, watch out for Listeria. She's a savage

3:49 That's so funny because you can tell she wants to laugh

[@existedkarma2765]

what does green poop mean

[@nottelling2976]

What if my freezer got everything down to absolute zero? Some viruses can survive that. Can Listeria? (I'm also building a Level 5 clean room sanitizer in front of my refrigerator thanks to this video.) :P

[@rakatudan3210]

I have one comment. I thought the freezer was supposed to keep that stuff safe.

[@showalk]

Soooo handle your food safely and cook it well... like usual?

[@Psychol-Snooper]

That intro reminds me of someone who said they did not know which end to point at the toilet.

[@Majoofi]

So if it takes two weeks to get sick, how can we even begin to identify the culprit food?

[@davidbrumley9203]

What about nuts? Peanuts, almonds, walnuts, pecans are all great foods, but how susceptible are they to listeria?

[@korvette21]

I find almost every one of these videos interesting. That being said, the requisite "eww" at the end of each episode makes me a little sad every time I see it.

[@mansdoctooor]

The animations are awesome !

[@jahking1268]

So the two week time frame you mention is that also the time frame in which illness will manifest in a human body?

[@jeffunger406]

Jae P

[@SlyPearTree]

I cook all meat to the required safe temperature except for beef, well ground beef is cooked all the way in but not a regular steak as I like it very rare (blue). My question is "Is listeria only present on the surface of meat or does it get inside?"

[@Gigaheart]

Blue is not very rare. Blue is a seared on the outside and rare in the middle.

[@eiserntorsphantomoftheoper2154]

My buddy always said" chop of the horns, wipe its ass, and wave it over a candle as you bring it in. Not rare, RAW. gross

[@SlyPearTree]

+Ima Tumor I say introduce the meat to the cooking tool (frying pan, grill etc...) but don't let them become friends.

[@denswonderyearschannel6026]

How does the bacteria steal that special molecule from its 'host', the white blood cell?

[@xerotoninz]

Is cooking the food not enough to kill it? What about microwaving the food?

[@makeupbliss9350]

My mum got an illness so bad I needed to stay at my friends house she's ok now that was years ago but it wasn't food poisoning she got it by salad and fish/ salmon

[@sooooooooDark]

is it just me or do u look better every episode?

[@aquaagproductions3269]

We go all organic . Dose that count?

[@asrirachaday]

What is "enough" time to cook food? Is organic raw vegetable diet at risk?

[@asrirachaday]

What is "enough" time to cook food? Is organic raw vegetable diet at risk? I use fresh vegetables

[@Mister_Facepalm]

I will never eat again.

[@paktofu123]

Where does listeria come from?

[@madisdeadchannel4608]

I'm scared now 😳

[@Distress.]

Now to throw away all those frozen vegetables.

[@OmegaMegalodon]

cook thoroughly and problems solved.

[@gregmiller9710]

...so it MUST be already present in foodstuffs before it is a danger..not just because i've left stuff in the freezer for eons??...

[@kathybones8552]

Yes, unless your freezer is contaminated.

[@gregmiller9710]

Kathy Bones afa i know it ain't, but i do need to throw stuff out, thanks

[@isaacwright385]

Would not placing food in the microwave for 10-15 seconds aid in distorting all harmful bacteria?

[@beinology]

It would help, but I'm unaware of a study that examines how long (or at what power) one must zap the food to reliably kill anything living on it. 10-15 seconds is no guarantee for safety.

[@elainelouve]

It needs heat is what I've heard, a certain temperature. Cook or fry the food. I don't know if a microwave works thoroughly enough?

[@paladincardona]

*AMAZING MY FREEZER IS DEATH ANTARTICA*

[@landonfade]

3:05 But if Listeria is a bacterium, doesn't it just contain RNA instead of DNA to be sequenced?

[@Bahzur]

That is, if i remember right, the case with a virus, not bacterium.

[@beinology]

Correct, Jajaid. Listeria use DNA to store genetic information, like most bacteria. Only a subset of viruses use RNA as their main genetic molecule.

[@KatoChaotix]

Sorry Blue Bell.

[@bethgadamali9127]

So wait, virus' s are mainly from RNA.. is bacteria based on a more complex cell like DNA? or a different form of RNA? parasites are complex cells though... im confused -_-

[@beinology]

Listeria is a bacterium: one simple cell big with a DNA for genetic information storage. Viruses are even smaller than that and some viruses are RNA-based while others are DNA-based.

[@ocktaprimadhi2834]

what about the natural killer cel

[@GunnerGibbons]

Another great vid thanks Anna

[@castellorizon]

*_''Quite Rare''_* TELL THAT TO BLUEBELL

[@victorfergn]

Gross Science or Scary Science?

[@fligleflorence1542]

got food positioning once at my younger brothers camp. was not fun.

[@nevaeh7952]

Me:eh Me after: IM NOT EATING ANYTHING

[@fluffyunicorn8779]

Yes

[@fluffyunicorn8779]

Hi

[@n7565j]

Ms Gross, Is Listeria something that simply passes with time, or is it something that needs antibiotics to get rid of??? Nice Video :-)

[@beatricebowlingzienkosky9828]

It needs antibiotics. Also, most of this listeria problem is caused by unsanitary production of our food. Such as vegetables, especially. Just wash them thoroughly. It is bad if you get it , I did from the lettuce they discovered was contaminated back in '15 and it is no picnic.

[@macyprevatt2551]

I had that but I didn't die I did get super sick though

[@sleepondirt498]

u cant rinse and scrub ice cream tho :(

[@Psymphonicmonk]

Now I'm just going to get paranoid. Want to bet MY government in South Africa has no way of tracking Listeria outbreaks? Obviously its also all the healthy food that's going to kill you while you suffer in agony ..... :O

[@pdthorn]

First gross science that left me uncomfortable and paranoid after viewing.

[@grossscienceshow]

Uh oh. Sorry, Paul! Was it the chicken on the conveyor belt? (Cause that part really got me.) Or just the overall concept?

[@pdthorn]

Yeah, the prospect that something I've frozen can make it out alive, into me and then wreck my whole everything left me unnerved for awhile.

[@claudiac.r.3693]

are there cures =l

[@justtrustme.3902]

"Halt" xD

[@ZoroarkChampion]

Was getting caught part of your plan?

[@ghostlycoast]

I’m shaming rn this is kinda scary

[@qirodraws]

well i just recovered from food poisoning, what a coincidence 😂😂

[@adamdunn8049]

dont when we cook chicken and other meats die?

[@foobargorch]

Does it give you a modern sexy look like botulism does?

[@beinology]

Does "modern sexy look," mean "deathly ill"? If so, then yes ;-)

[@foobargorch]

google "botox mistake" ;-)

[@gregmartens758]

Isn't that a redundant term? ;P

[@valken666]

I always boil some water, then throw vegetables in and wait until it boils again, then take out before eating. It doesn't cook, just kills all bacteria around the vegetables.
