Freezer smells
Back in the 80's, the AC company I worked for got a side gig killing pigeons.
They bought the largest chest freezer they could get, set it up in our unconditioned warehouse. Every morning, the Pest Bird employee would go to where they had installed the perches with poison that the birds absorbed through their feet at pigeon roosting areas and would pick up the dead pigeons, bring them back and put them in the freezer. In mid summer in Houston, some of those birds were just a bit on the gamey side.
People tended to stay away from the freezer area until after a couple of hours after it was opened.
Then late July, they found out, it was not meant to work in 100+ degree heat.
Took forever to air out the warehouse after it failed.
Weird thing about disposing of the pigeon carcasses-you could not take them to a standard dump-had to be disposed of at a toxic waste incinerator.
I guess they did not want the seagulls that hang around the dump to die after eating poisoned pigeon.
