ConAgra - which sold more than 100 million pot pies last year under its popular Banquet label — decided to make the consumer responsible for the kill step. The “food safety” instructions and four-step diagram on the 69-cent pies offer this guidance: “Internal temperature needs to reach 165° F as measured by a food thermometer in several spots.”

Increasingly, the corporations that supply Americans with processed foods are unable to guarantee the safety of their ingredients. In this case, ConAgra could not pinpoint which of the more than 25 ingredients in its pies was carrying salmonella. Other companies do not even know who is supplying their ingredients, let alone if those suppliers are screening the items for microbes and other potential dangers, interviews and documents show.

Yet the supply chain for ingredients in processed foods - from flavorings to flour to fruits and vegetables - is becoming more complex and global as the drive to keep food costs down intensifies. As a result, almost every element, not just red meat and poultry, is now a potential carrier of pathogens, government and industry officials concede. [Link]
