Warner, a business journalist, seems an unlikely candidate to write about food processing. The former journalist decided to satisfy her curiosity about expiration dates. The hole only got deeper from there. After six years, her growing stockpile of food hadn’t turned rancid or decomposed. But, the real spark for her investigation was when Warner’s mother accidently found some nine-month old guacamole in her daughter’s fridge and ate it. Granted her mother only had a small amount, but she suffered no ill effects. Warner became even more intrigued, so much so that her investigation expanded from researching Kellogg’s cereals to visiting soybean plants and attending cheese conferences.
