CAMP HILL, Pa. — With Hurricane Irene barreling up the East Coast and expected to make landfall in the Northeast this weekend, Rite Aid is stocking extra emergency supplies in its stores in affected regions, the retail pharmacy chain said.

Rite Aid stores in three states have increased supplies of bottled water, batteries, flashlights, canned foods, first aid supplies, disposable cameras and other items.

The American Red Cross recommends having a seven-day supply of medications and medical supplies, such as syringes, hearing aid batteries and glucose testing strips on hand.

Meanwhile, the Food and Drug Administration is urging people not to use food or drugs damaged by flood waters and to keep a supply of clean water available.
