I well recall flying workers to & fro a developing mining camp in The West back in the 90's. Industrial relations were strained betwixt said workers & their bosses. Maggots were a bargaining tool.
Introduced into the mess, they "aparrently" provided a reason to walk off the job, with claims of adulterated food.
Such a pity that the entomologist determined that the maggots were introduced from outside the region, and hadn't been deposited by a local fly!
Twiggy's come a long way since then.
