The Short Version
Cadbury is not selling "Eid Eggs" in UK supermarkets. The viral image is fabricated misinformation. Multiple independent fact-checkers (Full Fact, Snopes, The Journal) confirmed in February 2026 that the product does not exist. Cadbury's parent company Mondelēz International explicitly denied it. The social media account that originated the claim included "Semper parodius" (mock Latin for "Always Parody") in its profile. Cadbury's actual 2026 seasonal lineup includes only Easter-themed products.
