I always must stress, I can never tell if questions are jokes or not. I will answer it seriously, though.
Cookie dough is made of eggs, sugar, butter etc.
Rotten eggs are not entirely safe to eat, and gone off butter is not nice. It really depends on how expired the cookie dough is to be perfectly honest. If it has green bits of mould hanging off of it, I wouldn't try and eat it. But, it shouldn't do you MUCH damage, just give you a tiny bit of a stomach cramp if it is really badly off. So I wouldn't worry, although, if you feel incredibly ill and unable to do certain things, contact your local GP for expert advice.
I wouldn't reccomend it, ingesting something past due date especially 4 years ago could make you contract and illness or even result in death, but if it seems good enough to eat for you, go ahead.
It would have to depend on the mix
Premade browny mixs (any premade mixes cake, cookie or otherwise) should NOT be consumed if they are expired many of these contain things such as eggs which can make you seriously ill if consumed after they go bad.
That being said if it is a dry, add everything yourself mix then most likely it is still good, I've personally used dry mixes upwards of 2 years past their date with little in terms of problems (rising mixes not rising) and they've still tasted
The only ingredient that actual goes bad in cookie mix is the fat. It won't make you sick, but it may taste off since the fat may have gone rancid.
You should not eat any expired Food
No, hence the word expired. It is unsafe to eat anything expired. Dispose of anything expired.
you could die or at the least throw up
Not usually, no.
Of course it is!
I wouldn't eat a cookie that has been in the same box with a pencil.
ni you can get realy sick
Tollhouse cookie dough is definitely safe to eat after cooking thoroughly into cookies. However, because Tollhouse cookie dough is made with raw eggs in the dough, there is a possibility that the raw cookie dough straight from the package could make you ill. There was an outbreak of Salmonellalinked to eatin raw cookie dough somewhere around 2009 or 2010.
Yes, most Tinned/sealed food is safe to eat. The only time that it isn't safe to eat is if the "Use by date" has expired
It is safe to use an expired propane tank because it is a heat source and not an actual food. The only concern is if the tank is still safe to use without a risk of combusting.
You should not take any medications or dietary supplements that have expired.
Of course it is safe to eat turkey burgers however if you have allergy from turkey meat or the turkey meat is expired and out of date it is not safe. It is safe while you have a healthy turkey and you do not have allergy.
Yes. It is safe to heat and eat honey that shows an expired date on the commercial packaging.
