I think escorts are safer than casual sex, their job is at stake.
> FSWs were almost twice as likely to be diagnosed with chlamydia, and three times more likely to be diagnosed with gonorrhoea than other female attendees, adjusting for demographic factors.
The contamination is unlikely to come from raw food itself, chefs at restaurants are buying from the same retail channels as the rest of the people.
The source of contamination can be improper storage or handling, kitchen equipment, dishes and cutlery, people doing all the above. All these things are reused in restaurants.
> twice as likely to be diagnosed with chlamydia
See the table on page 347. For chlamydia, "period prevalence" figure is 10.1% for sex workers, 8.5% for other female attendees. That's 20% difference, not twice as likely.
Compensating for demographics factors is hard. You can surely compensate for the factor "young", can probably compensate for the factor "single", but how would you compensate for the factor "promiscuous", i.e. likely to go out and have casual sex? Because that's the demographic group people gonna sleep with, instead of sex workers.
