How toxic is industrial salt? (some food factories in Poland used it for sausages) [49]
All salt is poisonous, as is pretty well anything in a large enough quantity. Processed food contains plenty of salt - also refined sugar. Especially so in Poland to reflect consumer tastes. Wędliny especially contains lots of salt and also saltpetre (Postassium Nitrate). Small quantities aren't necessarily harmful however over time neither salt nor saltpetre are especially good for you.
Industrial salt however has several definitions - 'salts' might be a better word than 'salt'. It is these other substances (which vary according to the type of industrial salts used) that are the problem. All are dangerous in their own way. If it is pure salt (as Polsyr says, without iodine) there is no problem. If the salts however contain things unsuitable for food use it is a whole different matter.
The industrial salts thing might be a fuss over nothing, however it needs to be investigated immediately, products from the affected factories need to be taken of the market, the investigations need to be transparent and this could lead to huge international lawsuits.
This is particularly worrying since Poland is a major exporter of processed foods.
