0907 ET - Kroger says the cyclospora outbreak took a bite out of its sales in the second quarter, executives say on a call with analysts. The outbreak, which affected fresh produce, cost the grocery chain roughly 0.35 percentage points of total same-store sales growth, executives say. Same-store sales in the quarter increased 0.2%, missing Wall Street's estimate of 0.8%. The metric was also dinged by egg deflation, as egg prices have fallen from their peaks last year when there was a shortage. Kroger shares decline 2.2% premarket.
