A Warning To Parents

bigaudiofanatic

Hello I work at a dairy plant that make the milk for mcdonalds and also the milk for wawa. Here is the warning the bottles get sanitized with HI acid chem. to sanitize them. Well I noticed the other day that the bottles dont get rinse the just get turned upside down and whatever comes out comes out. The rest stays in there about a tbs. Just a little warning and this stuff is BAD working in a room with it makes your eyes burn. Just though I might warn you. I told the manager and he says its fine.:eek:

What is wawa? I appreciate this since our daughter drinks milk to no end. We don't got to McDonald's, so we are safe there, but I wasn't sure about the other.

Wawa is a convience store like quick check or 7-11

bigaudiofanatic

Wawa is a place like 7 eleven or a place like a delli and snacks store from NJ to about Virgina but they are planning on going all the way to cali.

I will buy nothing from a store named..Wawa.,,,,lol

tonyb

my WAWA hurts......:D

edbert

Ahh, I see. I was just hoping that wasn't another name for Walmart.

BottomFeeder

Wow. That's depressing.

But thanks very much for lookin' out!

not to derail but this reminds me of a funny story. i was riding down the road listening to a talk radio station and a local politician was running for some local office here in Va. long story short he was talking about our economy and how the price of bread and milk has gone way up. no lie this comes out of his mouth: "We don't even need dairy or bread farms anymore..if we want bread or milk nowadays we just have to go down to the store and buy some"

AdamRagland

needless to say the radio host ripped him a new one

Wawaaaaaaaaa!

Wawa is a Native American word for wild geese.

Wawa's are convenience stores, some have gas stations attached. The can be found from NJ to Ohio, some in southern NY too and as far south as northern Virginia in some spots.

For all of you bagging on the name and the store, you're foolish. No other convenience store comes close to the awesomeness of a Wawa. Every time I go on travel, I get angry at the town I am in because they do not have a Wawa.

Wawa's are usually open 24 hours and you can walk in there with 5 or 6 bucks and walk out with a meal. Wawa is also one of the best places to get Tastykakes and Entemann's products. More items that those of us in the PA, NJ, DE and MD areas have been accustomed to that the rest of the world doesn't know.

If Wawa sold beer, I'd park a motor home in the parking lot and live there. They are that awesome.

Don't knock the Wawa, man.

we have sheetz around my area. much like a wawa but i think i like wawas better

Budweiser beer factory has similar story which is also in NJ ironically....I was told the horror stories of cleaning the filters for the beer factory...they use chlorine to clean the filters. Ones used to clean the bathroom and stuff…nasty:mad:

I mean they do get free beer but no one really drinks any their own beer

Oh and about Hydrogen iodide:

From Wikipedia:

Hydrogen iodide (HI) is a diatomic molecule. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid. Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions; whereas, the other is an aqueous solution of said gas. They are interconvertible. HI is used in organic and inorganic synthesis as one of the primary sources of iodine and as a reducing agent.

http://en.wikipedia.org/wiki/Hydroiodic_acid

Essentially what that means is that the HI Chemical Wash that bigaudiofanatic is complaining about has a natural gaseous state. That means that for it to be a liquid, it either has to be under pressure or in an aqueous solution.

Aqueous solutions again from Wikipedia:

An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending (aq) to the relevant formula. The word aqueous means pertaining to, related to, similar to, or dissolved in water. As water is an excellent solvent as well as naturally abundant, it logically has become a ubiquitous solvent in chemistry.

So essentially, if the chemical wash does not have an aq after the chemical name, it is just a gas, pressurized. If that is the case, it likely evaporates long before any milk or other substance hits it. If it is an aqueous solution, rinsing will have little effect beside diluting the mixture further and would honestly be a waste of time. You could use a detergent to break the surface tension of the water to help remove the acid but then you have to find a detergent that won't react and you'll also have to worry about throughly rinsing that out too which adds cost and complexity for minimal benefit to the process.

However, more from Wikipedia about Hydrogen Iodide:

HI is a colorless gas that reacts with oxygen to give water and iodine. With moist air, HI gives a mist (or fumes) of hydroiodic acid. It is exceptionally soluble in water, giving hydroiodic acid. One liter of water will dissolve 425 liters of HI, the final solution having only four water molecules per molecule of HI.

What this essentially means is that the HI gas, once it hits oxygen, forms water, harmless stuff honestly and iodine which is found in lots of stuff and honestly not that bad for you at all in such small amounts. But the aqueous solution becomes dilute if the ratio exceeds 4 water molecules to 1 HI molecule. Meaning 5 or more water molecules to 1 HI, will drastically reduce the acid's potency.

So there are the facts. Be appalled if you want or don't be. HI Chemical Washes are used in lots of places for not only manufacturing but also food processing and such. I doubt that the milk in those containers is unsafe to drink and I'll bet that if you did some research, you'd see that quite a few dairies use the same kinds of wash as the dairy that packages the milk in question. It's not uncommon at all.


Am I the only one that paid attention in chemistry class?

Do the horror stories ever mention that the filters are ionized and part of the cleaning process is to restore the ionization? Restoring the ionization can be done by washing the filters with an ionized liquid like, say, chlorine. Which is also a disinfectant and sanitizer.

You ever go swimming in a swimming pool? Ever get water up your nose or accidentally suck down a big mouthful? Yeah, you probably got more chlorine in your system from doing that than you ever did from drinking Budweiser for years.

Wawa sammiches are amazing. That is all.

WaWa has great coffee!

wawa USED TO BE the best place on earth, because they used to have hot grills and you could get the meanest ****'ing sausage egg and cheese on planet earth.

in college we had one across campus and we used to make pledges go walk and get us them. When I was a pledge and had to go get them at 3am, we used to buy two for ourselves with the brothers money and eat one on the way back to the house and then enjoy another tasty treat once we got there... ahh that was when I was drunk stupid and happy..

You don't know what you're talking about. Wawa still does have hot grilles and you can get all kinds of sammiches from them. My favorite is the roasted pork on a torpedo roll with provolone and roaster peppers. That's a slammin' sammich!

Jstas, you can't learn everything from Wikipedia. Acids leave residues, regardless of whether they say aq or not. Sulfuric acid is never referred to as aq, but I can tell you from many years of experience in the chemical industry, it leaves behind sulfate crystals. Same with phosphoric acid, hydrochloric acid, caustic soda, nitric acid, chromic acid, acetic acid and many others that I've worked with for years.

None of this really matters because acids are natural inorganic atoms in solution. They are not poisonous unless they are concentrated enough to cause tissue damage. Acids are used in the food industry every day to preserve, adjust pH, or add to the flavor. The Beverage industry alone is one of the biggest users of phosphoric acid.

Acid left behind in milk bottles would not worry me in the least.

That doesn't surprise me or worry me. Gas tankers used to fill the rig up with gas and then empty out. Next load was a dairy farm to be filled up with milk. No washing, it was referred to as PPM.

Be interesting if they mixed the two up and poured the milk into the gas tank in the ground

I could just see people filling their tanks wtih a nasty milk/gas mix. :o

OK, so you didn't say anything I didn't already say.

On top of that, I didn't learn it from Wikipedia. I used Wikipedia as a reference to make my point. I learned it in high school and college chemistry.

No, I said that you were incorrect about the "aq" thing. Most acids will never be referred to as an aqueous solution. That is typically used to describe crystalline compounds that are dissolved in water solution. Things like salt, copper sulfate, potassium nitrate, etc.

My point was that acids leave residue and they very rarely just evaporate. Most are hygroscopic, so they absorb moisture from the atmosphere rather than evaporate it.
