Why do food delivery trucks have the word "fish" on them?

Trucks hauling fish are required to be especially identified because


of the danger of cross contamination if the containers are used for


other products, as well as odor control and other safety/hygienic


issues. The FDA regulates this, as they do other food


labeling/identifcation issues, and truckers hauling fish are subject


to inspection by the FDA as well as the normal DOT authorities, and


having the boxes labeled "FISH" facilitates this.





Sorry I couldn't find the exact reference, but hope this helps a bit.


At least we know it's not an entirely arbitrary thing. Oh - and along


those lines, I did find a reference to


someone receiving a ticket for not having their truck properly


labeled. See here: http://www.co.bexar.tx.us/jp/Parks___Wil鈥?/a>


Scroll down to "Commercial Fishing Violations." The person got a


$155.00 fine for it!


So it's not that there's no good reason, just that they're not


especially forthcoming about it outside of the industry - one of those


industrial secrets, I guess!
