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.
Most of the cases were due to the ST131 strain of E. coli, which emerged only a few decades ago and became a dominant strain. Over the decades, the organism has acquired additional resistance factors. ESBL E. coli has even had a rapid emergence in the Netherlands, a country where antibiotics are strictly regulated. In a recent study, 8.5% of 1,713 Amsterdam residents had ESBL E. coli in their stool samples.
