What happens if I eat mold?

A common concern people have is the outcome of eating food that is moldy. This happens when you are not paying attention to what you are eating and suddenly realize that you just ate half a sandwich made with bread that has some mold on it. Then you go “Oh, crap, I just ate some mold” and then you google it to find out if you are going to die ….

As with all things you eat, the first thing that must be said is this: If you are allergic to it, then you probably shouldn’t have eaten it. But, we’ll ignore that because if you are actually allergic to “mold” (or some subset of molds) than you already know what to do or not do.

Otherwise, the answer to the question is: There’s good news and bad news. First the good news. Mold is generally not bad for you (some molds are even good for you, or otherwise enhance food, as in those fancy smelly French cheeses). If you ate mold, just don’t worry. If you feel sick then maybe the mold is a problem, but most likely it isn’t.


Check out: The First Earth Day, an epoch journey into politics, explosions, folk music, and old boats floating on stinking rivers.

The bad news is simple: If the food is moldy, then it may be old and otherwise contaminated with bacteria and stuff that is not good for you. If you are in a high risk group for such things, or pregnant and trying to avoid listeria, etc., then you might want to avoid old rotten food, and the mold itself, while not harmful, is a clue that the food is old.


Check out our new science podcast, Ikonokast.

As a general rule, soft food is more risky if it is moldy, while hard food (like hard cheese) can be cleaned up by scraping or slicing away the moldy part.

In my personal opinion, First Worlders are more worried about rotten food than they need to be, and throw away a lot of perfectly good food. Try to be less squeamish and check your priv before discarding things that scare you.

    I certainly do not disagree with you. That said, I will now disagree with you and point out that some molds, particularly certain strains of Aspergillus species make mycotoxins, which can be problematic if not outrightly lethal. However, the mold growing on your bread is almost certainly a benign zygomycetes like rhizopus. I simply discard the mold parts or cut it away, in the case of cheese, and go on my happy culinary way.

    we have all noticed that the major brands of bread last much longer than the ones from the local bake shop.
    which makes me wonder if it’s better to eat bake shop bread that shows a moldy spot where perhaps the kitchen area was not %100 clean or go with the Big Brand that lasts and lasts and eat whatever it is they put into it to keep it “fresh”

    Oh no – the spores are everywhere! Except for the possibly horrible bitter taste produced by some of the common molds, most molds are pretty harmless (a few uncommon ones can produce toxins that’ll make you feel pretty miserable). However, I must admit that whenever I’m possessed to develop a sourdough culture I can’t help wondering if those white granules are a type of yeast I want or Candida Albicans – they all look alike to the unaided eye.

  6. #6 The Phytophactor
    April 22, 2012

    A yucky appearance and odor are microorganisms’ way of competing with the macrofauna for islands of resource. Getting eaten is the ultimate competitive loss, so the sooner the mold makes something look distasteful the more successful it is in obtaining resources. Unfortunately for some (those of smelly cheeses for example) we have learned to like the yuckiness thus demonstrating that in many cases the food is still edible but rendered distasteful, itself an instinctive reaction to help avoid those microorganisms that are not harmless. But this just shows what a competitor Greg is.

  7. #7 Greg Laden
    April 22, 2012

    PhytoPhactor, this copmetition theory has been around for quite a while and I used to think it a good idea, but I am no longer so convinced, for several reasons. First, it is very human centric; just because we are repulsed does not mean that other organisms are (plus as you point out, depending on the exact nature of the repulsive smell or sight, we may actually pay extra!). Second, if it is not backed up by truth, it is hard to defend; the noxious smell/look that covers something perfectly edible is not an evolutionary stable strategy.

    I’m wonding if there is something else going on.

    Sara, in well fed relatively wealthy western cultures we get to throw away food that is still edible but annoys us in some way or another. Like, it’s half eaten, has a bit of mold, is like something we ate for lunch and don’t want to eat the same thing twice in one day. That is a privilege we happen to have that others do not.

    Little itty bitty white spot on the crust- can I just scrape it off and eat the bread? I hate wasting a whole slice. I get the “hard food” rule but how contaminated is my soft bread?

  12. #12 Nicole
    January 4, 2013

    Also, toasting the bread- does that kill the mold and does that matter anyway? I keep my bread in the fridge because it lasts until its sell-by date that way, but my brother keeps moving it to the cupboard and it keeps getting mold spots within days of his doing that. I can’t afford to keep throwing out the loaves he moves out of the fridge 🙁 Good bread ain’t cheap!

    With bread and cheese I usually just remove the moldy bit and continue to eat it. However I just set my beer down in the garage for a few minutes, and when I went to take another drink I apparently picked up a different can that had been sitting there open for awhile. I took a decent smallow before the taste hit me, and when I dumped it out there was a thick skin of mold that came out… I should be fine though right? On the other hand I’m grossed out enough that it would be pretty easy to go purge right now.

  18. #18 Greg Laden
    June 23, 2013

    Catherine, probably no big deal. Just think of it as pasta sauce with a little extra cheese in it.

    But, it would have been better to not eat it because the mold indicates it is old, and has been exposed to air, so there could be bacteria in there you would not want to eat. But probably it’s not as bad as eating a three day old rotten monkey or something.

    I have to laugh at this thread… in a good way. I was wondering if the tortilla I ate might have been moldy because another in the bag was. It was from a local tortilla place in MX, and I knew it wouldn’t last as long commercially manufactured tortillas. I think I’ll be fine, even if there was a bit of mold on it (my smell check suggested there was not), and it was good to be reminded that this is a first-world problem. And, at that, many in our relatively wealthy western culture don’t have the same privileges to throw food away, either. As a teacher, I laughed both at the comments regarding “check your priv” (I did not know what that meant at first), and also #20’s response to her feelings about it. Any of us who have participated in this conversation should feel immensely blessed that 1) we can care about a ‘bit of mold,’ and 2) that we have the resources available to us to immediately check online to see what repercussions there might be. Thank you for reminding me of this!

    Several days ago while juicing raw veggies etc. I found mold growing on some of the foods. I cut the portions off the veggies, washed them and juiced them. i also discovered a little bit of mold growing on the exterior of my ginger root which had been refrigerated and as I cut it off I discovered that quite a bit of the inside was also bluish. I googled to discover that SOME ginger IS blue, but this was NOT the case with mine. It had started out whitish/yellowish. I continued to use it anyway thinking it must be from the cold/moisture in the fridge that turned it that color. The next day I was sick with fever, aches, and nausea/vomitting diarrhea. Now the reason I am puzzled is because I was also exposed to a stomach bug with those same symptoms two days prior while with my grandchildren. Soooo my question for you is: Do you think I was sick from the ginger root or the virus? Would those be the reactions/symptoms of eating moldy food? I have quite a bit of green juice with ginger I would still like to drink !!! Thanks so much for your time and knowledge.

    I found a Britia water bottle in my cabinet that I used two years ago when we went to Disney. It had some water in the bottom but did not smell. I washed it out and used it at work. I had rinsed off the filter and thought it was fine. I drank about half the bottle of water, 6 oz. and my stomach has not felt right. It just aches, I have no appetite and I feel like I drank mold infested water! Is it in my head or did I make myself sick? Any suggestions for feeling better?

    I bought cherry preserves yesterday at the supermarket. The expiration date is October 2015. I opened it and in the corner there was a small amount of white. I thought it might be crystallized sugar so I scooped it out and threw that part away. I took a few teaspoons and put it on my toast then put it in the oven (I eat my jelly hot) it didn’t occur to me it might be mold. I’m 38 weeks pregnant will we be ok. What should I look out for?

    Be careful of you are allergic. Once I ate some green peppers which were 1.5 to 2 weeks old, already cut up in tupperware. I was working on my computer picking it up and dipping it in hummus. Less then 20 minutes later I got hot and cold flashes, my heart rate and blood pressure increased…I felt dizzy, had some problems with trying to breathe….couldn’t swallow my air…..several coworkers at the hospital I worked at thought it was a heart attack. I went to ER…they kept me overnight couldn’t find anything wrong. Kept commenting while I slept that I had low to good blood pressure. After all the tests they said my heart was normal, my cholesterol was only 2 points to high (great for being 110 pounds overweight!) Had no other medical 8 sues contributing to this mysterious heart problem.
    And they couldn’t find 1 reason for my “heart surge”. 2 weeks later I was recounting story to an EMT friend who pointed out my symptoms sounded like an allergic reaction. My moral is, if you have quick or reactive type allergies to mold don’t eat it and get help right away. I don’t let my food so long and if I forget about food in the fridge, I throw it out. I won’t go through that again.

    I live in a pretty small town on one acre of land. I have a very large garden. This is my first time growing sunflowers, and when I picked the seed heads, they had mold on them. Being very busy, I left the seeds in the basement still on the seed head for about 2 weeks. I took the seeds off the seed heads, sorted them (removed the moldy ones), and rinsed them in water. About a day or two later, I boiled the seeds in salt water and then roasted them. When I tried them, the seed inside the shell was a brownish black. The seeds themselves smell like McDonalds food and were kind of squishy and weird. NOT a good sign! Several people have eaten them. My mom says they are fine. I bet it’s fine this once but should I throw them out? I have about 3-4 gallons worth of seeds (my garden is not small). I don’t want to throw them out. It seems very wasteful. Should I? Will they hurt me and anyone who eats them. Also, y’all are saying all these things about bread, freeze the bread until you are ready to use it. A little mold can be cut off. I can tomato sauce, salsa, pickles, and marinara sauce. The veggies I use to make the stuff are NOT the kind you would choose at the grocery store (they are moldy and have often sat around for several weeks. Looks can be very deceiving. I just cut off the bad parts and cook them. I’m still perfectly fine and so are everyone who has eaten them. So for a little mold, just cut it off. You won’t get sick, trust me.

    Kudos for still responding after two years. Two things would be helpful.

    Most mold that grows on our food is probably safe. But one might want to watch for symptoms. Of course, most of our antibiotics are made from mold, directly or indirectly! (in theory).

    I would worry more about the other stuff. If food is moldy, has it gone off in other ways? Is there a lot of bacteria in it?

    I just ingested .4 of a moldy blueberry muffin by accident. I’d take the word of the other comments, but this is a gluten-free Udi’s muffin: do different types of molds grow on different types of flour (rice, tapioca, almond, etc), or am I safe? The mold I see is in small white patches of spots at the top (abt .6 cm across), and in gummy, semi-transparent white strands running down the sides at sparse intervals. It’s been 20 minutes since I ate it, nothing yet, but I’m a bit concerned.

    Also, some clarification could be appreciated: if Tums/other antacids help your stomach, but the acids are what break down the molds, wouldn’t taking an antacid make any problems last longer?

    Celia R., I read a story a while back in Discover Magazine that documented a woman who ate some old peppers and had an allergic reaction to them that started off with tingling lips. Further symptoms did not appear until the next day, though.

    Hey ya’ll,
    I’m still alive, barely, Lol. The cold I was fighting turned into a full on flu type thing now I’ve got bronchitis. I felt ok after I wrote in, just told myself I was fine. And I was, until the sniffles morphed into this thing. So it confirms the mold I ate inside the date does not help ward off colds and such. In my opinion it just made it worse, but who knows its probably just the nasty flu going around my area. Mage I think eating peppers always makes your lips tingle due to the capsaicin, and the lady could have been allergic to that. My conclusion is I ate the mold I’m still alive, I feel like crud but I don’t think the mold had anything to do with it. But I’m not gonna go and eat moldy stuff, ha! Our bodies are strong, and can fight so many bad things we put in it. I really wish I could know the type of mold it was. Peace

    First of all, the food industry uses many unappealing foods and just lies to you and tells you it’s fresh and 100% natural. Second, the reason major brand bread lasts so long is because it’s filled with chemicals to preserve freshness. I’d rather eat moldy bakery bread than “fresh” major brand bread. And finally, stop being a bunch of pussies. Stop wasting huge amounts of foods because of a little bruise or blue spot. I eat lots of old foods and I haven’t been sick in two years. I also boycotted the pharmeseutical industry, vaccines, and went vegan and 100% natural.

    My wife just bought a 1 Kg (2.2 lbs.) box of dates from a Russian shop down in Pompano. They were priced low because (guessing) they’ve been in that shop a long time! They are a little hard, outer skins are a little dry, but semi-moist and look good enough inside. Tasty! After we’d both tried a few I noticed a dull, blue-gray, almost powdery tinge in the recesses between the ridges of the wrinkles. Not being from California or western Asia, we’re not very accustomed to the norma appearance of dates. I’ll write in with any symptoms, should they occur… unless I’m dead, of course!
    P.S. For a guy with so acute and adept with the English lang, I’m [surprzd at your shortning of “priv.”] I thought you were using the British term “privy,” and advising us to check our stools after we’d ingested suspicious food! 😉

    I was eating a honey bun earlier and ate almost half of it, some of it tasted a little funny, but I thought it was probably normal. Then I saw a brown piece in the middle and thought it was the cinnamon they put in it (which it probably was). When I got into the middle of it, I noticed some white fuzzy stuff and some kind of bluish looking texture. I started freaking out and told my mother, in which she tried to calm me down and assure me it wasn’t mold. It had blue on it, what else could it be? And on top of that, there was the white fuzzy stuff on it. I tried making myself throw up most of it. Got a little bit of it up. Then I drank some baking soda, and it helped get a little bit more up. Didn’t clean out my whole stomach, but I should probably be okay, at least I hope.

    Ok so this morning I didn’t have an appetite but I had raspberries for breakfast anyway because I felt like I needed to eat something. Some of them looked a little too ripe but they looked ok to eat. After I was almost done, I saw one that looked kind of moldy to me, so I didn’t eat it. After that was when the burping began (and it hasn’t stopped all day). Several hours later, after I took a shower, and immediately afterwards I vomited up all the raspberries but I felt a little better afterwards. Several hours later, I forced myself to eat a little tomato soup even though I had almost no appetite and I had some earl grey tea because I was so cold. After feeling nauseous for several hours, I once again vomited but felt a little better. I am afraid that all of this is because I ate some bad raspberries. I have an allergy to mold (usually just a runny nose/maybe a little sneezing) and I’m afraid that eating those raspberries may have caused the whole thing. Your thoughts?

    I had bought a box of Girl Scout cookies a while ago and started eating some without looking without They tasted kind of bitter but I was like “lol whatever” and kept eating them. After the fourth one I looked down into the box and realized they were all moldy and shit. I feel kind of stupid but fine otherwise.

    So, silly me, I wanted a yogurt drink and felt adventurous so I got strawberry-banana kefir. Got home so late and just couldn’t wait to try out, took a big swig and was appalled. It was fizzy, the way mandarin oranges are if they’ve been out too long. I intended to storm the local Wal-Mart and demand a refund but fortunately I procrastinated. Long enough to google kefir. And learned that is it’s nature and all about the wonderful things it can do for you, using helpful bacteria to combat bad stuff in your colons, and replace bad bacteria with good which we rely on to survive. Huh. So I downed the rest of the large bottle and felt great for days. So, just like some mold is beneficial (penicillin if you aren’t allergic, which I am) and some bacteria are good as well (cultures in red wine, kefir, who knows what else), our bodies usually have the ability to resist bad stuff (even bacteria, poisons and viruses) if we build up resistance over time.

    Oh My Goodness! Some o’ you guys are hiLARious!!! Meant to do a quick read cuz my berries (mainly blackberries and raspberries) tend to grow white fuzzies before I get to enjoy’em all…but ended up reading this to the end. I may never come back here, but thanx for the encouragement that I shall live with some mold I may have ingested here’n there without realizing it, and making me totally CRACK UP after getting off of work @ 3am! Sat in my car in the driveway for about 15min reading replies before I got out to walk in the house and read more ^_^

    As for milk, I prefer it “normal” but my friend’s mother of Albanian descent, from Macedonia, takes the milk, ferments it into a type of buttermilk, which *I* cannot stand the taste of (except buttermilk biscuits or doughnuts!). Also…the Japanese (of which I’m half) have a dish called “natto “which is feremented soy beans…and they LOOK, SMELL & TASTE like spoiled beans!!! I tried it for the 1st time with my ramen set, lady warned me I should try something else but I said I wanted to try it because I know several friends who love it, and I almost DIED (not from food poisoning, but cuz of the TASTE!)! TRIED eating a lot of rice with it, but could not handle the slimy texture and smell…nor taste! AU YA!

    Had my tonsils removed and everything was going just fine – pain level was a low #2 on the scale – I was eating soft foods such as bananas, yogurt, peaches, easy to eat soups, etc. – thought I was doing just perfect until my mother gave me some cut strawberries which I ate, then after about five of them, I saw the green mold. Three weeks later I came down with a very severe facial palsy. Could it have been the mold I digested that caused this disease?

    well a few months back i recall chewing into a massive date at work. I noticed that this date was cooler than usuall and was very powdery. I soon began to cough paroxysmally with desperation before I realised what had just happened. I immediately ran to the kitchen and drank water (my teeth had black powder and everything else). The coughing was quite bad! It was like an unintentional version of eating a spoonful of cinnamon powder like that youtube sensation many moons ago done by certified idiots of our society.

    i was fine the next day I didn’t die or antyhing like that.

    i’m on here again because it just happened again today with another stupid date! This time I didn’t happen to inhale the dust but still ate a bit.

    I was and also am now completely sobre and intact with my senses, so there was no high or psychedelic experience.

    I agree that all the posts are too funny. I sprayed some redi whip on my pancakes, afterwards I noticed mold on the ridge of the sprayer/spout. Gross! That means someone in the house probably sprayed it into their mouth!

    I canned spaghetti with meat sauce 3 weeks ago. I went into the cellar and noticed white/greenish mold on the inside of a few canning jars. the seals were still good. I cooked the sauce about 12 hours prior to putting the food in canning jars. The jars sealed. I didn’t reprocesses the jars in the canner.
    I have today taken all mold at the top off inside of all jars and recooked the good sauce. I am starting the process of canning the jars now. Do I have to worry about toxins in this product in the future. Is this safe. I am going to put in the cellar for a couple of months before we use. Do you think this is enough time.

    For a few days my mother has been using lots of vanilla creamer that I’ve commented to her about as seeming to have curdled bits in. But its artificial I think, not natural dairy. I just opened the lid and found green mold floating near the surface.

    My question is this. Fresh raspberries get mold within a few days. However if I mix them in a large container of yogurt they seem fine for a week or more. Do they actually get moldy, but I can’t see it, or are they protected from mold once mixed into the yogurt?

    If you are eating a hamburger bun and you did not notice mold on the bread then when you decide to go to bed and you feel like a wierd feeling that you might puke is that a sign that the mold is getting make sick.

    Thank you all, especially the creator of this post, for reassuring me that I am (probably) not going to die. I was so hungry, so I grabbed some chips and hummus out of the fridge and started just blindly eating it. I had 3-4 chips with pretty big scoops of hummus and thought it tasted weird, but that maybe it just needed to be stirred up. So I grabbed a spoon, went to stir, and looked down to see mold all around the whole container!!! Well, except for on the top layer of course, since I had just scarfed that whole part up. My first reaction was: I should go puke. Second reaction: I hate puking. Then, I sent a text to my husband to see what he thought about it (his response: You’ll probably get high). Lastly, I decided to Google it to see if I was going to die, which brings me here! I needed the laughs, and I had many good ones while reading through this! I must add that I love “check your priv”. Fingers crossed that I’ll make it through this first world problem. Thanks again, everyone!

    I have an allergy to penicillin, (it caused a severe itchy rash and liver damage last time I took it). About an hour ago I drank down a glass of pure orange juice, which seemed OK to begin with, but then when I swallowed the last of it, there was a disgusting sick and bitter taste, I looked at the base of the glass and it had white slime with blue speckles in it. Any idea if this is penicillin and if this will cause me any harm? My tongue feels sore, is red and slightly swollen.

    I had trouble shaking some black pepper out of a metal shaker. Shook a small amount on my food & ate it. Later I checked the pepper container— smelled like mold . Unreal ! Got on your blog. Got such a small amount, I am not too worried. But that was DEFINITELY a first. Moldy pepper? ” Godfry Daniel”, as WC Fields used to say. Just for curiosity, is there any danger from this?

    @Erin, Me tooo!!!! I just hate hummus and crackers. I googled this and this thread came up because I too just ate some crackers and hummus that I now see has mold, AFTER already eating half. What makes it so bad is that I usually love hummus and this was just really bad. Not just that it has mold, but it was just not a good recipe. Was wondering if I was going to be sick!!! The moldy part was under part of the top that I had not peeled back. I’m curious what brand yours was. Mine was L**ly. I won’t type the whole thing in case it is not allowed.

    Thanks for the informative article, and thank you even more so commenters, for the intrigue. So, last week I had some friends over, they brought me a crème brûlée. I thanked them politely for their fancy pants food and shoved it to the back of the fridge, claiming that I had just eaten as sly ruse. Anyway, I was fairly hungry just earlier, so I took the crème brûlée, and started micro-nibbling it, I couldn’t quite a get an idea of what it tasted like as the particles were really too small, so I progressed with a more mainstream type of nibble, about halfway through it, I spied a tiny, what I could only call specket, of something. It was purple and a bit flaky or perhaps fuzzy, at first I thought it was moving but then I realised my head was wavering due to my staring so intently. I tried to pick it out with my fingernail, yet I only drove it deeper into the as yet unexplored crème brûlée. So, I immediately put the crème brûlée down, I can’t stress that enough. Then I started pacing around the crème brûlée as it lay on the counter, trying to nonchalenty observe it. I am at a loss on how to proceed, any suggestions ?

    This thread is making me guffaw…a lot.

    I got here because I ate some hummus in the dark and was a new kind for me (with rosemary). I just thought it was the new taste, but lo and behold, I went to put it away in the fridge and noticed it was swirled with blue/black. I’m assuming mold, because rosemary is not blue nor black. I’m not worried because I’ll pretty much each anything. That might kill me one day, I guess…

    I accidently took one drink of a soda on my night stand that had grown mold, thinking it was my drink from last night. This was at 6am and it is now 8:45am and I don’t feel sick or anything. Since it was just one sip, will I be okay?

    So I just took a huge swig of Kefir smoothie only to realize after that it expired on 01/01/2016!!! Thats 2.5 months past the expiration date and I just bought it from the health food store 3 hours ago! So now ofcorse, I am completely freaking out and and worried that I just ingested something that is going to make me very sick! 🙁

    When making my PB&J this morning, I saw a little white dot in the strawberry jelly. Wasn’t sure what it was, so scooped it out and continued making my sandwich. I just ate lunch and it didn’t taste bitter and I didn’t see any mold growing. Do you think it was mold and do you think I’ll get sick?

    Just ate a piece of commercial beef jerky that unknown to me, was laying on top of a very moldy piece. The taste was off, but I finished that bite. It was when I looked into the bag that I saw it. No one has mentioned mold on meat. What do you think?
