Kegs and weed killer

[Special Hops]

Yes... don't you think Pepsi and Coke got a few kegs back over the years that had been used to spray chemicals? You clean them... where do you think it would be a problem?

If you are going that route are you sure everything you wasn't at some in a container containing containing chemicals. I am pretty sure it's against FDA regulations. But you never know I guess.

1. Stainless doesn't absorb anything. It may have substances adsorbed to it, but depending on the behaviour of the substance in question, that should be relatively easy to take care of.
2. The dose makes the poison. You probably ingest more herbicide from eating improperly washed fruits and veg than you will from using these kegs that you will probably wash the ass out of. If you can't taste it or smell it, its probably not a huge concern.
3. Whoever said it will absorb things and then not release it until it releases into your beer, this is absolutely ridiculous. What about beer do you think is so magical that it can dissolve chemicals that nothing else would touch. If that is the case with your homebrew, please don't ever ask me to do a bottle swap :cross:

What?

Take it easy francis, the poster was using sarcasm.





The kegs may very well be fine after you clean the sh!t out of them. I'd be happy with the use of caustics but, then again, I have them on hand. Anything less and I'd not even consider the use of those kegs.

Not like you are out any cost since they were given to you.

I never swap bottles with people that can't see sarcasm anyway...

that guy is a jerk, why ruin kegs?!

there are products made to neutralize pesticide residue and clean them out of sprayer tanks. i tend to agree with the crowd that says it's possible to use these for beer, if you do a very thorough job of cleaning, the amount leftover to possibly harm you is probably negligible. here is an example of one of the products i mentioned:

The FDA has a cleaning procedure. Do you think the tanker truck that is going from Washington to New York with your kids apple juice is returning with maple sirup? Do you think for a tanker to be 'food grade' it can only haul food?

Your a homebrewer, you have a 10 gallon brewpot. I would poor in 5 gallons of boiling water. Let it set a spell. Repeat. Replace o-rings. Boiling water with a scoop of ozi-clean. Starsan. Use.

i'm no scientologist, but if i was a weed, i would definitely stay away from weed killer.

 

[dallasdb]

Can you pasteurize them somehow?

Would that guarantee a clean and poison free vessel?

It may not come back empty, but I'd be extremely surprised if it is loaded up with pesticide and then flushed out and filled back up with apple juice. A quick google search came up with the April 2011 "Model Tanker Wash Guidelines for the Fruit Juice Industry" PDF. In section IV. Tanker Requirements, it reads in part:

a. Only food grade tankers are to be used and are to be permanently dedicated and clearly identified “food grade.”

b. Only approved food products, ingredients, or potable water shall have been hauled in the tanker. (See VIII- Tanker Wash Type Based Upon Food Commodity Previously Hauled).

(and in the referenced section VIII it specifies that items not on the table and certified food grade may not be hauled). I'm no expert, and this is just one example, but I am strongly inclined to believe that Food Grade generally means always and only Food Grade.

Regardless, I think you'd be extremely ill-advised to take the advice of a random Internet unknown on this subject. I'd get advice and procedures from a reliable source and be sure I understood the procedure well enough to know what the risks actually are.

Hit them with a caustic wash(drain cleaner) and an acid wash (star san acid #5) and you should be good to go. Most of the cleaners and washes used in production facilities are worse than most lawncare chemicals. Change your seals and poppets and get some beer in them.

I'm pretty certain that a caustic wash and acid wash are far worse for you than glyphosate(LD50 of about 5000Mg/Kg)
Give it a good hot water rinse, change the o-rings, you'll be fine.
Glyphosate is an amine salt formulation, 100% water soluble. It will just wash away.

 

[annasdadhockey]

Your talking about the same chemicals they spray on our food right?

Anyone ever hear of Roundup ready crops?

Technical material was fed to rats and dogs at dietary levels of 200, 600, and 2000 ppm for 90 days. No significant differences from control animals were observed in mean body weight, food consumption, behavioral reactions, mortality, hematology, blood chemistry, or urinalyses. There were no relevant gross or histopathologic changes.
Two-year feeding studies to rats and dogs and rat production studies at dietary levels of 30, 100, and 300 ppm have shown no adverse effects (54).
Tests on the biologically active ingredient in this formulation (glyphosate) showed that glyphosate did not cause any mutagenic,
carcinogenic, teratogenic (birth defects), adverse reproductive changes, or neurotoxic effects (55b).

With an LD50 over 5 gm/kg. This stuff kills plants, period.

A lot of drinking water is overalls contaminated with multiple pesticides any way. Long island has tested positive for overm 90 different kinds at minimal levels. I wouldn't those kegs.

 

[TheZer]

Well, the warning label does say that if ingested, drink plenty of fluids.

A caustic wash, followed by an acid wash, is how the food processing indsutry cleans all of their stainless steel equipment.

No pesticide chemical thatI've ever heard of has the power to infuse into stainless steel. A good cleaning and fresh seals and I would be fine with it.

It's not like we are talking about plastic fermentation vessels

 

[Dean Palmer]

Would that guarantee a clean and poison free vessel?

Pasteurization is a heat process that kills organisms and has nothing to do with clearing chemical contaminants. All you'd have would be warm chemicals.

 

[jonp9576]

if you are going to use them, replace the presure relief on top too. there is a cheap rubber seal in there, and you can get new screw in relief valves for under $5

 

[annasdadhockey]

Not sure if that's true or not, but it's funny.

 

[Chowe]

I would not use them.
