Esophagogastroduodenoscopy (EGD) is a diagnostic procedure that allows the physician to diagnose and treat problems in the upper gastrointestinal (UGI) tract. The doctor uses a long, flexible, lighted tube called an endoscope. The endoscope is guided through the patient's mouth and throat, then through the esophagus, stomach, and duodenum (first part of the small intestine). The doctor can examine the inside of these organs and detect abnormalities.
Onions are transported in wide-meshed jute fabric or plastic bags, crates, boxes, cartons, baskets or fruit crates. Small-meshed bags are unsuitable for transport due to their low permeability to air.
1 Pantry time shown for storing onions assumes storage in a cool (45Â° - 55Â° F) dry area with good air circulation; if such an area is not available, refrigerate onions. To freeze onions: (1) Peel, then slice or chop onions; (2) Place in airtight containers or heavy-duty freezer bags, or wrap tightly in heavy-duty aluminum foil or plastic wrap. 2  Freezer time shown is for best quality only â foods kept constantly frozen at 0Â° F will keep safe indefinitely.
