Taking a closer look at my 10kg bag of table salt (NaCl) I noticed it has a diffrent anti cake agent (535). After a bit of searching I found out its Sodium ferrocyanide, while its fairly inert apparently it can decompose to hydrogen cyanide. I prefer magnesium oxide personally, inert and insoluble

Am I being over cautious here?

Yes.

Sodium Hexacyanoferrate II is yellow so you'd notice if they put loads in.

From some WHO human studies infants tolerate 0.0077g/Kg with no ill effects measured.
So very roughly speaking a 75Kg (11st -ish) adult will tolerate 0.6g.
A typical maximum quantity (1999 UK statutory level) in salt is 20mg/Kg (really effective anti-caking agent!)
To reach the max for infants a 75Kg adult would need to eat 30Kg!

Feel free to knock my arithmetic, even if I am out by a factor of 100, it's still safe.
