Let’s face it; it is often easier just to refill your work coffee cup without washing it beforehand, but do you ever feel guilty or ashamed about doing this? If so, worry no more because not washing your coffee cup could actually be better for your health!
There are those in the office who would never dream of making a second cup of coffee without washing their mug first, but these are the people who could be exposed to the harmful bacteria that may be living in the office kitchen sponge.
A recent article published in the Wall Street Journal focused on the dangers of washing your work coffee cup. Journalist Heidi Mitchell interviewed Baylor College of Medicine’s paediatrics professorJeffrey Starke, who said, “If you leave cream or sugar in your mug over the weekend, that can certainly cause mould to grow. However, if you finish your coffee and leave minimal residue in your cup, you could pour yourself a fresh cup the next day and not do yourself any harm.”
He went on to say that there would obviously be germs found in an unwashed coffee cup but pointed out that most these germs would have come from whoever used the cup.He said, “Due to the fact that most harmful bacteria die shortly after leaving the body, you could drink from your coffee cup while sick and still not re-infect yourself.”
He went on to say that the most germ-filled thing in an office is the washing-up sponge in the kitchen, and concluded by saying, “Most of the most sanitary options you have when it comes to your coffee cup upkeep DON’T involve actually washing it.”
However, this only applies to those who have black coffee; when milk and sugar are added, it is a good idea to rinse your coffee cup with hot water.
