E. coli outbreak linked to chicken salad

Nineteen people in seven states have contracted E. coli in an outbreak linked to chicken salad bought at Costco, federal health officials said Tuesday. People who bought chicken salad at any U.S. Costco store on or before Friday were advised to throw it away, even if no one has gotten sick. The strain of Shiga toxin-producing E. coli can be life-threatening, but no deaths have been reported in the current outbreak. The CDC and state health officials were investigating and have not yet determined what ingredient in the rotisserie chicken salad made and sold in Costco Wholesale stores could be the source of the outbreak. People have fallen ill in California, Colorado, Missouri, Montana, Utah, Virginia and Washington. The outbreak is not related to a recent case involving Chipotle restaurants in which 40 people were sickened.

Job worries help sink consumer confidence

Confidence in the economy eroded this month as Americans became more worried about the job market. A business research group said Tuesday that its consumer confidence index fell to 90.4 in November, down from 99.1 in October. The index is at its lowest level since September 2014. The share of Americans surveyed by the Conference Board anticipating more jobs in the coming months fell. Fewer people also expect to see their incomes increase. The percentage describing jobs as "plentiful" declined to 19.9 percent from 22.7 percent. The decline in the confidence index comes after a robust month of hiring in October.

Amazon forces some password resets

Amazon has forced an unknown number of account holders to change passwords that may have been compromised, just as it heads into one of the busiest shopping days of the year. Tech news site ZDNet first noted the issue after multiple readers reported receiving an e-mail saying that the online retailer had reset their passwords. They were also notified of the change through the site's account message center, ZDNet reported, which confirmed their legitimacy. The e-mail sent to affected users said that the company had "recently discovered that your [Amazon] password may have been improperly stored on your device or transmitted to Amazon in a way that could potentially expose it to a third party," according to ZDNet. The messages said there was "no reason" to believe passwords were actually revealed to a third party and it was taking action out of "an abundance of caution."

Nobel winner for economic history dies

Douglass North, who won a Nobel Prize for his studies of how political, social and other noneconomic forces shaped the economic growth of nations throughout history, died Monday. He was 95. The Royal Swedish Academy of Sciences awarded North and University of Chicago economist Robert Fogel the 1993 Nobel in economics "for having renewed research in economic history by applying economic theory and quantitative methods in order to explain economic and institutional change." Both men were pioneers in applying modern mathematics to the study of history, a field known as new economic history, or cliometrics, after Clio, the muse of history in Greek mythology.
