Clean Monday
Clean Monday is a public holiday in Greece and Cyprus, where it is celebrated with outdoor excursions, the consumption of shellfish and other fasting food, a special kind of azyme bread, baked only on that day, named "lagana" () and the widespread custom of flying kites. Eating meat, eggs and dairy products is traditionally forbidden to Orthodox Christians throughout Lent, with fish being eaten only on major feast days, but shellfish is permitted in European denominations. This has created the tradition of eating elaborate dishes based on seafood (shellfish, molluscs, fish roe etc.). Traditionally, it is considered to mark the beginning of the spring season, a notion which was used symbolically in Ivan Bunin's critically acclaimed story, "Pure Monday".
2013 horse meat scandal
Observant Muslims and Jews consider it sinful to eat certain types of meat, pork for both groups and also horse and many other animals for Jews, due to religious prohibitions. Professor Reilly stated "for some religious groups or people who abstain from eating pig meat, the presence of traces of pig DNA is unacceptable".
On 15 March 2013 it was confirmed by a Westminister wing on Health and Safety that pig DNA had been found in halal chicken sausages produced for schools.
