Good idea.

I am posting my findings in the Food Safety forum as well in case others are curious.

Cool thanks for the update. I like confidence they have in stating it will not "bother" the fish. I am sure their lawyers would prefer different wording than that though :) In any case that is more than enough to assume its safe enough anyway.

I have used it to glue a few things back together. It is great stuff.

So here is an update regarding the food safety of the Gorilla glue I used to make my "sausage". I sent an email to the company asking what the MSDS meant. Here is their reply:

Dear John Comito, 

Thank you for contacting The Gorilla Glue Company. We have built our family owned business on the honest belief in our products and a desire to provide the best customer service possible.

 

You are correct.  The MSDS Sheet is when the product is in it's liquid form.  Once cured for a full 7 days, Gorilla Glue Dries White is 100% waterproof, it can be submerged, it is non-toxic and totally inert so it will not leach anything into the water to bother your fish.  Be sure to follow the standard directions and "Damp It", "Glue It" and "Clamp It".  Lightly scratch up any non-porous surfaces first where the glue will be and plastic applications will be 'trial and error'.

 

I hope this information is helpful and again, thank you for contacting us. If you have any additional questions or comments, please let us know by e-mail or by phone at 1-800-966-3458 from 8:00 a.m. - 5:00 p.m. Eastern Time.

Sincerely,



Mary Ellen
Customer Support Representative

I agree about adhesives! If the thing works well enough during its test run, then the plan is to sew them instead of glue them. I have a good friend in the canvas business, and she could have 10 or 20 of these things sewn up in no time. I think I'll plant this first one out and let it ride for about a month. If it grows out well, then I'll replace it with a sewn one, and maybe a few more.

I'm no expert at reading the finer details of MSDS so I would also be interested in what others have to say. Just the fact you are aware of it is really the main point. With AP it is of particular concern only because it is a recirculating system so even very small amounts of something less than great can build up over time.

I am with you on "how safe is safe enough". I think that is subjective. Adhesives in general seem to be something people are weary about and is always worth looking into.

Look forward to the updates on the "sausage".

Thanks Chris. I just checked the MSDS and it is acutely toxic to fish:

12. ECOLOGICAL INFORMATION
Do not allow the product to escape into waters, wastewater or soil.
Biodegradability 0% after 28 days
Bioaccumulation Does not bioaccumulate.
Acute toxicity to fish LC50 > 10,000 mg/l (96 hrs.)
Toxicity for daphnia EC 50 > 1,000 mg/l (24 hrs.)
Acute toxicity to bacteria EC 50 > 3,217 mg/l (24 hrs.)

 I'm no chemist, but it sounds like it would take a lot of the stuff to be a problem. The other question is if the MSDS is referring to the product when new and still in liquid form, or after it has dried.  I did some other research and found some folks saying it is food safe. They could not sell it for the purposes and uses that they advertise if it were not. Such as ceramics, china, glass, etc. I feel that any toxicity is bad, so I will be finding a different product unless I can find good proof that I should not worry. I thought about it before I used it, and came up with the logic I described above. I'm glad someone brought it up because I am still curious. Any Chemists out there that can answer this?

Is Gorilla glue food safe? 

You may want to look into that more. http://www.gorillatough.com/index.php?page=msds
