The dirtiest things in a restaurant aren't what you'd expect

A food court employee was recently sacked for using a fruit knife to scrape dead skin off her hand at a food stall.

Just a little over a month ago, another employee of the same food court chain, Kopitiam, was also fired after she was filmed washing a shoe in the sink of a dessert stall.

Both cases are a reminder of the importance of high sanitation standards at eateries. But how do you determine whether the one you're dining at is clean?

The filthiest items in a restaurant are sometimes not identifiable with the naked eye, a report by The Daily Meal has revealed.

If you think it's alright to drop that lemon wedge into your drink after squeezing it, think again. According to The Daily Meal, the lemons used for garnish at a restaurant are most likely not washed beforehand and are likely to have been left out in the open for a whole day (or even longer!).

The culinary website also named salad bar tongs as among the 11 dirtiest things in every restaurant, claiming that they're "basically as dirty as the toilet flush handle".

Ketchup bottles and salt and pepper shakers aren't that much cleaner, either. Having remained on the tables for most of the day, you don't want to imagine the amount of germs that has built up on them.
