Wal-Mart Stores called Friday for meat suppliers to their US operations to curb the use of antibiotics and follow globally recognized guidelines on humane treatment of farm animals. The push was directed at suppliers to Walmart US and Sam's Club, which counted on groceries for more than half of their annual revenues last year of $346 billion. "Our customers want to know more about how their food is grown and raised, and where it comes from," said Kathleen McLaughlin, senior vice president of Walmart sustainability.
Janet Yellen said Friday she expects the Federal Reserve to begin raising interest rates "at some point this year," saying delaying the long-awaited move risks the economy overheating. The comments came two days after minutes of the Fed's policy board made clear that slow economic growth in recent months meant it was not expecting to increase the benchmark Fed funds rate before July, despite earlier forecasts of a mid-year hike. Yellen said she expects the economy to bounce back from the stall in the first quarter, but that any decision needed to be based on clear improvement in the data.
