The truth about double-dipping

Double-dipping might seem gross, but what does the science actually say about it?

I worked at a scout camp clinic during a norovirus outbreak that saw 10% of the camp have encounters with us in the worst week. Somehow, and I have NO idea how, but somehow through all of the handwashing, routine 3x/day bleaching of all surfaces, etc, I managed to avoid symptomatic infection. I was the only one working in the clinic who did not get ill. Totally insane. Because we had a dark sense of humor, one week when our nature lodge people got hit hard, we awarded them a "staff infection" award at that week's campfire.

[@synchronium24]

Viral load still matters, presumably.

[@Dr.Hiccup]

I mean ya probably, but that doesn't mean you shouldn't take risk minimizations anyways. Would you rather be at a party where someone has a disease but everyone is wearing masks, or a party where everyone is making out. Obviously this is a dramatic example but it applies to lesser extent to double dipping. Regardless if it's a communal bowl you shouldn't double dip because you don't know if others are comfortable with it. If it's close friends and none of you care then who cares

[@theletters9623]

I remember the mythbusters episode about double dipping where they found out that their control dip (one with zero dips performed) had just an insane amount of bacteria in it already, because bacteria is everywhere and a lot of it doesn't do much.

​@@umi3017yeah really liked their idea of sterile salsa

[@HeroDarkStorn]

That was my first thought, how does adding ~10k matter when there are uncountable millions already. There was also the 5-minute rule episode, which annoyed me because they didn't test the difference between 1-microsecond rule and 1-week rule. That is, to me, touching the ground at all is the major "infector", leaving it there for seconds or days should make no difference (of course ignoring natural spoiling of food in time)

[@RedSaint83]

Ohh, right, that's the episode where they had to make an over pressurized sterile tent to keep it as clean as possible.

[@Zaxares]

My rule of thumb is you only double dip with people you live with (if they're not grossed out about it). Under those conditions, chances are that whatever diseases they have will definitely be spread to you anyway via talking, sneezing, sharing the same bathroom or bedroom facilities etc. At public or other gatherings, don't double dip; it's the equivalent of standing over a bowl of food and open-mouthed breathing on it. Sure, the actual risk is probably not that high, but it's still gross. :P

[@ElJosher]

[@masterkevkev]

@@Connie_cpu And the idiotic reason is that these very germ-carrying nimwits go "I didn't touch my ass/genitals, so my hands are fine" - Say the person who touched the initial dirty doorknob opening the bathroom door (let's say it's a push door so they never touched it), who then will touch their pants (Let's assume no belt-handling/leather), to at least open a fly/hole (if male) to then piss (Let's say they literally have no underwear) at a urinal that will *not* 100% dodge their own hands/body from splash-back (Worse chance at a urinal instead of a toilet, so let's assume toilet - all the positives here), and somehow do all this without touching the door to the stall they took to use said stall in said bathroom.... and then perfectly took a paper towel sheet from a dispenser that had no paper out visibly to begin with and has no bacteria (somehow) throughout the slot it's sliding through - automatic with a hand sensor - *JUST* so they can then open back the bathroom door with the paper towel to not take bacteria from others who do the same but worse so they could leave. In the *near perfect* (even a germaphobe would make a mistake here) scenario, you've still transferred bacteria from your pants/pockets/fly (that I'm sure is 100% clean and totally not blown against with dust, touched by anything else, surgical level fine) to your hands. In that near perfect scenario, people who do not care about bacteria have to agree that they don't mind me (or anybody else) wiping my hand against my pants crotch region or ass cheeks (on the pants), and touching a dip or drink they're going to consume. If you're fine with me grabbing my crotch for a few seconds and then putting my finger in your dip - then fine. But if that disgusts you - that is the *near perfect scenario* amount of bacteria transferred from someone who just used a public bathroom (or in the party instance, a bathroom at someone's house that others have used and for some reason has a paper towel dispenser, a push door that doesn't lock or shut without key... you know the impossibility of this but you get the point) to handling a chip. By the way, this is all explaining *hand* bacteria transfer. We haven't even double-dipped. If what I've explained is already far enough - realize that the chip didn't even double dip. Realize the chip didn't even touch the mouth. It just entered the dip once, and has transferred what the hand has; And this is a near perfect scenario of someone who didn't wash their hands. Not tryin' to put the fear of the world to everyone, but know at every party (no matter how well you know your friends (idiots or not)), someone has that mentality of never washing their hands. Every time you are consuming something that isn't perfectly sealed to the second you touched it (like a bottled drink, or a bag of chips), mentally accept you're fine eating (or drinking) something that has ample pants-transferred crotch/ass bacteria already in it. Enjoy the info 😇and pray to whatever you pray to that the lovely-lovely individual isn't carrying an incurable virus/disease.

One significant vector at parties, particularly ones where people are talking loud and standing close is just HOW MUCH we spit when talking and that spit will inevitably land on the food you're holding and are about to eat. These droplets are also inhaled and land in your eyes and mouth directly. There were several studies during COVID which detailed this but I don't have the links handy.

if your concerned about the bacteria in the bowl after double dipping, but just cant get over the urge to not double dip, just use the OTHER side of the chip, the one you havent bitten into (note: this works better for french fries but ehh)

[@Kripahhhhh1402]

Most of the time people will just gonna forget about this and then eat this and that while double dipping normally. It doesn't even matter because the part of the chip you touch are going to make a contact with the dipping anyway.

[@chestersnap]

There's only three cases where I double dip. The first is if I'm the only one eating it (oh no I got my own germs). The second is if I'm only sharing with my family. The last is if it's a large enough item that I can turn around to dip again without any part that my mouth touched getting into it

[@nahor88]

The large item is the main problem, at Texmex/Mex restaurants in particular. Tortilla chips tend to be very unusually shaped, and the bowl of salsa tends to be small. If the restaurant is busy, you may not get any small plates to go with the chips and salsa, and asking for them takes forever. The only alternative is breaking the chips apart by hand, which is messy and can actually spread even more bacteria.

I feel like double dipping is frowned upon in western cultures is from gatherings of strangers. Most of the other examples you gave of transferring germs/bacteria are things that only happen between people friends and closer. Having the control over who you trust to keep clean is important and you lose that control at a party where people double dip. It also seems like such a small and easy thing to change so why not just avoid double dipping in those situations...

[@dracknoid3015]

Growing up Asian, almost all of our meals and snacks were communal, family style. Everything in the middle, you had a bowl of rice, you had your chopsticks you reached in with your chopsticks. No questions asked. The only time separate chopsticks were used were if you were actively sick like with a cold. And so when I encountered the whole "Ew double dipping" thing at friends birthday party I was very, very, very, very confused, and thought they were concerned because it was with fingers, so the next time I went to the party I brought chopsticks to pick up chips and stuff, which...led to a whole other round of "this chick doesn't understand American manners". Jokes on them, because years later a few of my friends from that time were like "I eat chips and popcorn with chopsticks now, my fingers are clean."

I'd say the biggest party risk these days is *phone-sharing* -- cell phones are *disgusting* and I don't get why it's become so normal for people to grab them in order to see things and then just go back to their normal stuff without washing their hands. And I'm still annoyed at the friend-of-a-friend who used his used chopsticks to grab food out of the communal dish I'd bought for the group and then, when informed, basically said "that's just who I am and you better get used to it." (Not the only reason we were at odds on that trip, but that one really riled me, in the midst of a *pandemic* of all things.) But yeah, there's a lot of unknowns -- though also, one would expect that cultures where food-germ-sharing is the norm would actually have better immune responses to that norm, and that people from food-germ-aversion cultures who just decide to suddenly switch modes... well, I understand there's a reason that travelers, not natives, deal with Montezuma's Revenge: their immune systems aren't used to the onslaught. I'd say there's enough reason for me to (a) avoid parties with a lot of people to begin with (yay introversion!) and (b) maintain some level of aversion reaction to shared saliva.

I feel like if someone is really really worried about getting sick from double dipping the easiest thing to do would just be pour some of the dip from the jar into a little personal bowl or something.

[@aabbccddeeff782]

Hi Kate. I have a thought that could be a topic for next video. What makes a steak (or any piece of animal protein) chewy, how to avoid that during cooking, or how small should a piece be cut to make it chewable.

[@nothanks39]

i think one of the factors is the fibers in the meat. you can take a knife and score the meat to cut some of the longer fibers, resulting in a more tender steak

[@DaShikuXI]

The strength of the protein chains in the meat is what makes it tough. When you heat up meat the protein chains firm up and become stronger, which makes the meat tougher. The evaporation of moisture also makes the meat dry and harder to chew as a result. The way you avoid this is by not overcooking the meat. Muscle fibers also have a layer of collagen around it, which adds to the hardness of the fibers. Those collagens need to be heated up until they dissolve, removing the hard outer layer. This means you need an adequate temperature for cooking your meat, and time for the collagen to actually dissolve. This is why sous vide is a great method of cooking meat for example, as it keeps a consistent temperature over a longer period of time.

I already don't double dip, but if I'm sick, I make extra sure that I don't. But that can't necessarily be said for everyone. I would not dip out of the same bowl as somebody else who double dipped into it. Not sure I've ever actually been anywhere where that has happened. The times there is a communal bowl, like salsa or queso at mexican, none of the people present double dip, so there is no issue. Also, I like to think it works, but I will often times flip over what I dipped and dip the side that wasn't exposed to my saliva into the bowl, so technically double dipping, but not double dipping in a way that puts my saliva into the bowl.

[@SPAJ92]

Grab a chip from one edge, dip one side in one dip and another in another dip, then eat. Then you get the benefits of double dipping without going back for more

i wonder if erasmus didn't approve of double dipping bread into soup even if it was one's own soup. that's pretty severe. but i could imagine if we're conditioned not to want to see communal double dipping we might then also not want to see it done publicly at all even in a personal bowl...since they might not have been thinking just in terms of germs back then but wanting to follow proper form

[@AykevanLaethem]

[@tonysplaining1114]

Can you do food sharing as well?

[@QPoily]

In the end it's all about social etiquette. When there's a divisive topic like this, it's rude to ignore the side that takes issue with it and default to the side that doesn't take issue with it. That's not how being considerate works since the people who don't care simply get a slightly blander chip, while the people who do care get their entire experience ruined. One is LESS of a net plus, while the other is a net negative.

[@astaiannymph]

While it's good to know about the science and different cultures' approaches, in the end, it's best to be considerate to others.

main issue I take with double dipping is that it does affect the shelf life of the dip in case the dip isn't finished in that sitting. Especially relevant for things like bread spreads and people double dipping their knives.

double dipping expands our mouth microbiome and as such is a public service.

[@silvershoelaces3976]

I don't care if the risk is low. Low is not zero. My mom gave me a cold sore when I was 11 because she drank out of my glass (without permission!) and now I will have a cold sore for the rest of my life. I am never sharing a drink with someone or double dipping ever again.

[@Rarkss]

because she was sick but most likely you are gonna be fine but keep being paranoid dont know how to fix that

[@rymlks]

Did this study also control for bacteria transfer from single-dips? The argument about salsa seems like it would apply whether the chip had been bitten or not - there's plenty of bacteria on the hand already ready to drip into a bowl

[@segevstormlord3713]

The real sin of double-dipping is that you're leaving your digestive enzymes in the dip. This will actually cause it to get gross, and the more people contributing enzymes, the sooner the dip will get gross-looking as the stuff in it starts to digest right in the bowl. XP

[@PhilBoswell]

Question. If I grabbed a small bowl and spooned some sauce for myself (so that my double dipping doesn't go into the communal bowl), is that a socially acceptable behavior? or will some people think I'm being impolite or otherwise inappropriate in some way? Also, China here. On the one hand, chopsticks and dips do cause some spit swapping, most people don't care, but on the other hand, there are some of public service posters and TV reports advocating things like communal chopsticks or single-bite things to dip (so that you don't need to dip twice).

[@MsSagittariusA]

I don't think that's rude or weird. That's what I typically tend to do. I don't like the concept of double dipping and also don't like having to repeatedly go back for more dip lol

[@runnerfrog13]

In the US, typically it's only impolite if you are double dipping from a communal dish. When it's your own serving of the food (like spooning yourself some of the food into a personal bowl), nobody really cares how often you re-dip into your own serving.

[@670839245]

@@runnerfrog13 I was concerned about the "spooning sauce for myself" part being impolite, because the education in my culture gives me the impression that it might feel inconsiderate for some people

[@DrPotato0]

What if you flip the item your dipping away from the bitten part

[@Korrant]

I usually take a bite then turn the chip around and dip again but on the other side of the chip I hadn’t eaten from

[@eliezerkraiman414]

You forgot to mention people spitting into your food while they're talking. That can happen a lot at parties sometimes especially when people talk loudly

[@macsnafu]

:01 Freckles! Asking the important questions, yeah! The solution is have a small enough piece of food so that after one bite, there's not enough to dip a second time. Simple, I know, but people don't seem to think of it. And perhaps, not always easy to control.

[@archivethearchives]

First, from one freckled person to another, yours look so cool. Second, the way in which food is served and shared is a very nuanced thing in my home. Something like a shared dip bowl would be very inappropriate to serve guests. If anything like a dip were served, it would be so they can allot themselves a serving on their own plate. Sharing food together in the way you described other cultures is something we only regard as for family and loved ones. I would find it very inappropriate if an acquaintance or friend was made to eat from something like a shared dish of dip. It would not show respect to the guests. When my auntie and I are sitting together, we share food from each other’s plates or sometimes eat from the same bowl or plate. But that is not something I would do with a friend or acquaintance, right? I am sure many feel the same way. It is not just because of the germs, but a matter of respect. Touching someone else’s food is offensive to some.

[@jasonreed7522]

From my american perspective the big food sharing rules are: 1. The other person must consent to giving you their food. 2. Already segmented foods like french fries or popcorn are considered sharable because you can remove some pieces with contaminating the rest. 3. Something eaten with utensils like a bowl of ice cream or mashed potatoes can have 1 bite shared so long as the utensil is clean and the removed piece of food was from an untouched part of the plate. 4. Double dipping is mentally gross, as is eating after someone else regardless of the actual hygiene of the situation. And this last one isn't a rule but significant others generally have a higher willingness to share food in ways that involve higher risk of spit swapping. Although the exact degree is between them and no one else. (But others can be grossed out by it) And related to food sharing is drink sharing, the original owner of the drink determines the rule for how the other person must consume it. Normally the asker must "waterfall" if anything less than a close friend.

[@MathewSan_]

Nice video 🔝👍

[@SilverScarletSpider]

4:11 5:01 Double dipping is still disgusting in food settings where sharing of food, slobber, and saliva is non-consentual. For example a party is full of strangers. I am more than willing to share a saliva, food, and drinks with sexual partners, close friends that I trust, or some family though.

[@Mortyrian]

Did the study also do a control where people dipped once?
