Borax in caviar

We're not scientists but we don't think this should be an issue. The fact that it is comes form a ruling made by the US Food & Drug Administration decades ago that Borax may not be used as a food additive. This seems to be based on the fact that it can do nasty things if you consume it in meaningful quantities like a couple of grams a day.

However, long before the FDA came into being, European caviar producers had discovered that a tiny bit of borax added to caviar helped to ensure give it that nice firm bite that is part of the caviar brand. So adding a trace of borax to caviar became standard practice throughout Europe. And when European food authorities considered the safety issue - and being unaware of any harms caused by borax in caviar - they gave it the nod. All caviar (we are aware of) marketed in Europe lists E285 in its ingredients. That's borax.

With the result that some Americans think European caviar could hurt them. Well, if you're super cautious, you might want to avoid it. But despite researching the issue on Google, we found no evidence that anyone ever recorded harm arising from the borax in caviar.
