Allergy question: Do all plaster companies use the same type of glue?!

Although I do not work in the plastering business, I have been in manufacturing for the last twenty years in the food business.

Every company sources out its own ingredients and very many times we change our sources also due to costing, supply and demand, availability etc.. So the chances of you running into the same glue source is pretty slim from company to company.

But you also have to remember, any one of those companies can change at any time. You will have to keep checking to verify your safety.
