on who you ask.
• Iowa officials say that almost 150 cyclospora infections in their state were linked to a bagged lettuce mix and the threat is over. Federal officials at the Centers for Disease Control and Prevention and the Food and Drug Administration aren't so

sure, saying it is too early to say if the outbreak is over. There are almost 400 illnesses total in 15 states.
• Here are some answers to frequently asked questions about the infections and the outbreak:
• Q: What are cyclospora infections?
• A: Cyclospora infection, or cyclosporiasis, is caused by parasites that are spread when people ingest food or water contaminated with feces. People who are exposed usually become sick after about a week and have bad diarrhea and other flu-like symptoms that can last from a few days to a month or longer if untreated. It's common to feel tired and relapse is possible. It's not generally contagious and can be treated with antibiotics. Deaths from the infection are rare.

NSA acknowledges its '3 hops' get millions of Americans' phone records, not just terrorists

• WASHINGTON (AP) -- President Barack Obama's national security team acknowledged for the first time Wednesday that, when investigating one suspected terrorist, it can read and store the phone records of millions of Americans.
• Since it was revealed recently that the National Security Agency puts the phone records of every American into a database, the Obama administration has assured the nation that such records are rarely searched and, when they are, officials target only suspected international terrorists.
• But testimony before Congress on Wednesday showed how easy it is for Americans with no connection to terrorism to unwittingly have their calling patterns analyzed by the government.
• It hinges on what's known as "hop" or "chain" analysis. When the NSA identifies a suspect, it can look not just at his phone records, but also the records of everyone he calls, everyone who calls those people and everyone who calls those people.
• If the average person called 40 unique people, three-hop analysis would allow the government to mine the records of 2.5 million Americans when investigating one suspected terrorist.
