ELI5: Are food products that say "consume within 7-10 days after opening" basicslly a food poisoning gamble after day 7?

Why not just say consume within 10 days if there isn't a slight risk after day 7? If there is a risk after day 7, why not just leave it at 7?

usually, that is a freshness date and not a you will die if you eat it after  date. 

If properly stored and packaged, most food doesn't have germ risks before you open it. 

But  something like a cookie could lose its taste or firmness or whatnot. 

Once you open something all bets are off. You have to be really careful to keep it at the correct temp. 


Like if you leave out cheese dip for hours it can get germy. If you eat it again later you could get sick.
