Hydrogen peroxide is not a treatment for whooping cough

Whopping cough cases in the United States reached levels in 2025 far higher than before and during the Covid-19 pandemic. But social media posts recommending hydrogen peroxide as a remedy are misguided; the illness can be prevented with vaccination and fought with antibiotics, experts said, while the liquid composed of hydrogen and oxygen is an unproven and potentially dangerous treatment.

Greek mayor does not feature in old X Factor video

Tilos is home to fewer than 1,000 permanent residents, and is a popular tourism destination in the Dodecanese group of islands in the Aegean Sea. A recent rescue of dozens of migrants and refugees by the port authorities on Tilos led to a clash between the island’s mayor, Maria Kamma-Aliferi, and a tourist, who the mayor claimed had called for the displaced people to be thrown into the sea. The tourist denied this in a Facebook post.

Claims that the image of a mother was removed from Greek milk cartons fuel anti-LGBT sentiment

In January 2024, Greek Prime Minister Kyriakos Mitsotakis announced a bill aimed at legalising marriage and adoption for same-sex couples. On February 15, Greece’s parliament adopted the landmark reform, making the country the 37th in the world – and the first Orthodox Christian one – to legalise adoption by same-sex families. This is a significant step for the country, as previously, the state did not recognize parental rights for non-biological parents (archived link here).

This artefact does not come from Sparta and the technology behind it has been explained

False claims that a Roman chalice actually hails from ancient Greece and boasts mysterious colour-changing properties returned to social media in January 2023, following the latest talks over the British Museum’s possible return of the Parthenon sculptures to Athens. In reality, the ancient cup has been dated back to Roman times in the 4th century AD, is known as the “Lycurgus Cup” and has been proven by scientists to change colour in different lighting thanks to traces of silver-gold alloy in its glass front.

No, Frontex has not warned that 330,000 migrants will arrive in the European Union in 2023

Online articles and social media posts widely shared in Greek at the end of January 2023 claimed the EU border agency Frontex had warned that 330,000 migrants would enter Europe over 2023 after the same number had arrived the previous year. These posts are wrong. The agency said in a news release that it had counted 330,000 irregular entries into the EU over the 2022. It made no projections for 2023. Frontex’s figures include people who cross borders several times and so are counted several times, which has caused confusion before. The International Organization for Migration (IOM) estimates 188,000 people entered Europe illegally in 2022, which researchers say is a more reliable figure.

Product codes starting with the number eight do not identify genetically modified produce

Fruit and vegetables labelled with a five-digit product code starting with “8” have not been genetically modified, contrary to what has been claimed in posts shared hundreds of times on Facebook since December. While it is true that the prefix “8” was initially intended to label transgenic produce, the International Federation of Produce Standards (IFPS) – which is responsible for establishing Price Look Up (PLU) codes for fruit and vegetables – has never used it in this way. Product codes beginning with 8 will be used to designate new products in the near future. Under Greek law, products containing genetically modified organisms – or “GMOs” – must be clearly labelled as such at the point of sale.
