PROBLEM: (CNN) -- The discovery of horse DNA in hamburgers on sale at supermarkets in Ireland and Britain is testing the appetite of meat lovers there. The Food Safety Authority of Ireland said Tuesday that 10 out of 27 hamburger products it analyzed in a study were found to contain horse DNA, and 23 of them tested positive for pig DNA.

The horse-tainted burgers, on sale at several different supermarket chains, came from two meat processing plants in Ireland and one in Britain, the Irish authority said. "This raises concerns in relation to the traceability of meat ingredients and products entering the food chain," it said, but noted that the findings posed no risk to public health.

In nine out of the 10 burger samples, the horse DNA was found at very low levels, the authority said, but in one sample from Tesco, Britain's largest retailer, the horsemeat accounted for about 29% of the burger. Tesco responded by pulling from its shelves all products from the company that had supplied the dubious burgers. Read more: How severe weather makes people go hungry . "We understand that many of our customers will be concerned by this news, and we apologize sincerely for any distress," Tesco said. The retailer is working with Irish and British authorities and the supplier to work out what had happened, it said. Alan Reilly, the chief executive of the Irish food authority, said there was a "plausible explanation" for the pig meat finding its way into the burgers, since meat from different animals is processed at the same plants. But he said there was "no clear explanation at this time" for the presence of the horsemeat. Report: Unsafe food putting lives at risk . "In Ireland, it is not in our culture to eat horsemeat and therefore, we do not expect to find it in a burger," Reilly said. "Likewise, for some religious groups or people who abstain from eating pig meat, the presence of traces of pig DNA is unacceptable." Many British and Irish people expressed their distaste over the revelations on social media. Read more: Horse -- coming soon to a meat case near you? Some Twitter users said they weren't surprised to hear about the questionable origins of the burgers, while others debated the ethics of eating horsemeat. And then there were those who saw an opportunity for attempts at humor. "Going to #tesco and expecting a beef burger. Instead you get #horsemeat . Sounds to me like foal-play," wrote Twitter user Matt Oswin under the username @BrushmanLestar.

PROBLEM: (CNN) -- There's some magic coming to a British stage. Author J.K. Rowling has announced she is developing a play based on her "Harry Potter" stories. According to her website, Rowling is working in collaboration with award-winning producers Sonia Friedman and Colin Callender on the project. "Over the years I have received countless approaches about turning Harry Potter into a theatrical production, but Sonia and Colin's vision was the only one that really made sense to me, and which had the sensitivity, intensity and intimacy I thought appropriate for bringing Harry's story to the stage," Rowling said in a statement. "After a year in gestation it is exciting to see this project moving on to the next phase. I'd like to thank Warner Bros. for their continuing support in this project." Warner Bros. is owned by CNN's parent company, Time Warner. Rowling will reportedly be a producer of the play and work with a writer, but she will not be writing the play. The story will follow Potter in his early years as an orphan. Directors and writers for the play, which will go into development in 2014, are currently being considered.

PROBLEM: (CNN) -- Just when cruise lines thought they might be headed for calmer waters ... At least 162 passengers and 11 crew members have reported being ill on board Princess Cruises' Caribbean Princess, according to the Centers for Disease Control and Prevention. The institute said health officers would board the ship in Houston to investigate the gastrointestinal illness, which is causing vomiting and diarrhea. The news follows reports of sickness this week on another cruise ship, this one from the Royal Caribbean line. Nearly 700 crew and passengers fell ill aboard the Royal Caribbean's Explorer of the Seas, the highest number of sick people reported on any cruise ship in two decades, CDC data show. That ship returned home Wednesday, two days earlier than expected. To compare the cruises, 5.22% of passengers on the Caribbean Princess reported being ill, versus 20.5% on the Explorer of the Seas. The outbreak on board the Caribbean Princess has been confirmed as norovirus, according to Julie Benson, a spokeswoman for Princess Cruises. Are cruise ships floating petri dishes? Noroviruses spread easily and are a common cause of gastroenteritis, which produces vomiting and diarrhea. Norovirus is also suspected on board the Explorer of the Seas, though the cause of the illness there has not been confirmed. Caribbean Princess is expected in Houston early Friday. The seven-day cruise is being cut short by one day. Sick passengers are being asked to stay in their cabins, while staff disinfect public areas such as restrooms and elevators. The decision to cut the trip short was made based on forecasts for heavy fog, not the outbreak, Benson said. CNN first learned of the stricken Princess ship from a Twitter post by the Houston Chronicle. Royal Caribbean cruise ship returns home - with a sickness record .
