World Microbiome Day is observed worldwide every June 27 to educate the public about the essential role of microorganisms in natural processes and to highlight achievements in microbiome research. Launched in 2018 by APC Microbiome Ireland, the day aims to combat stereotypes surrounding microbes, emphasizing that the majority are beneficial rather than pathogenic. Participants can engage by learning about microbiomes, attending events, or organizing their own activities, often using the hashtag #WorldMicrobiomeDay on social media. Each year features a new theme; for instance, the 2023 theme focused on "Microbes and Food," highlighting the role of microbiomes in food production and digestive health. Microbiomes, which include various microorganisms such as bacteria, archaea, and some fungi, are integral to human health, ecosystem balance, and food systems.
