Roast the vegetables. Place the baking sheet with the vegetables into your preheated oven, on the middle or top rack. Roast for 15 minutes to an hour, depending on the vegetable. The vegetables are done when they are cooked through, the centers soft and creamy and the outer edges golden and crispy.
E. coli O157:H7 first became a household name during an outbreak in the western U.S. that began in late 1992, and lasted into 1993. The E. coli outbreak was linked to the consumption of hamburgers served by the Jack in the Box Restaurant chain.
â¢ In the ten years following the 1982 outbreak, approximately thirty E. coli O157:H7 outbreaks were recorded in the United States (Griffin & Tauxe, 1991). It is important to note that only about 10% of infections occur in outbreaks, the rest are sporadic.
