Question
In Estonia, the product bought from the shop lasts about 2-3 days, in Finland 3-5 days and In Oslo Norway 7 days.
The better infrastructure of transportation explains some for Finland and Norway. But how on earth so big difference between Norway and Finland?
I heard today that some countries are fluoridating milk. Ii is not in Finland and Norway. However, it may be the case that some minerals are existing naturally more in Norway than in Finland. Also, more rain dissolves more minerals in Norway than in Finland.
How can pasteurized milk last 7 days?
Explanation / Answer
I would rather think about regulatory differences instead of biological ones. (Edit, as also Rory M highlighted in a comment)
Extended shelf life can be obtained through microbial ultrafiltration. However in Europe, ultrafiltration labelling is not mandatory, so it is difficult to distinguish if a milk product was simply pasteurized or also ultrafiltrated. The converse case, biologically speaking, two milk products could be generally the same but one country could be more stricter than the other on shelf-life legislation. (The shelf-life relates more to the unsuitability for sale rather than for consumption).
