One local pest control company even stated that 40 per cent of coffee machines they check have cockroach infestations in them
Around October 2017, there was news a McDonald’s customer in Bangkok found cockroach legs floating in his coffee cup. Yes, cockroach legs. So he asked the staff to replace his coffee. “But when the employees poured another cup, it seemed that they found more cockroach legs in the coffee. I felt even more terrible,” he wrote in a Facebook post on McDonald’s Thailand’s page.
According to a report by Channel NewsAsia, pest control companies in Singapore have said that cockroach infestations are incredibly common in coffee machines at cafes. One local pest control company even stated that 40 per cent of coffee machines they check have cockroach infestations in them! Eww!!! A representative from the company told the daily,
“German cockroaches are commonly found at F&B outlets and they are small enough to hide inside these coffee machines.”
According to a Singapore coffee machine supplier, Cedric Ho, cockroaches tend to infest fully automatic machines and not professional espresso machines at cafes. He stated that this was because fully automatic machines use thermoblock technology instead of boilers, saying,
Those machines used by professional baristas are very unlikely to have cockroaches because the boilers inside are huge and very, very hot. Any cockroach that lands on one of the metal pieces inside will probably be fried. But the fully automatic ones do not have boilers, and are not very hot. So the cockroaches will go inside, make a home and have a good time.
According to Ho, most hotels and offices use fully automatic machines, “If the office pantry is not well-designed and is moist and not well ventilated, I suspect you will also find cockroaches inside those machines.” He then advised that the best way to prevent such infestations from occurring is to place these machines in well-ventilated places and also avoid leaving leftover food near the machine.
