This is true of warehouses everywhere, not just ones in underdeveloped countries. Developed countries just usually have a higher turnover and distribution closer to production sources, so they sit in storage for less time.
As a truck driver, I can tell you that most warehouses are extremely clean and pest free, with empty rodent traps all over the place.
Except for the Dollar General Distribution Center in Indianola, Mississippi. That place was horrifying, trash and spoiled food everywhere and rats running around like they owned the place.
I've worked at a few warehouses picking orders and I second this. At least in the US health and building codes require rodent traps and inspections happen regularly. While I'm sure infestations happen businesses that want to stay open follow the law and get pests under control.
It's amusing seeing people who clearly haven't spent time in warehouses tell internet strangers that warehouses have rats.
Wow, in other manufacturing I’ve had to call something “biologically contaminated” to mean that the bird infestation in the warehouse is out of control but we can’t convince anyone to pay to fix it
Do you drink the soda with gloves and by holding it 5 cm from your lips? Exactly like this you also don't just clean the upside of a dish or the usable part of knives, forks etc.
