Mega food companies like ConAgra, whose frozen chicken pot pies sickened over 15,000 people two years ago, are giving up the ghost and admitting they have no idea where many of their ingredients come from nor how they’ve been handled.

Sound like a food safety nightmare? It is, but companies are increasingly pushing the burden of dealing with it onto consumers.

ConAgra now instructs pot-pie eaters to heat the product in a conventional oven and measure the temperature “with a food thermometer in several spots” to ensure that it reaches 165 degrees.
