No, there is no correlation. The main thing with listeria, just so you understand, from all the risk assessments that have been done is that you really need to have fairly good growth of the organism to reach levels that actually cause disease. For example, let's say a listeria cell fell on a raspberry. Because the conditions within the raspberry are very acidic, you would not actually get any growth of the organism and you would probably get inactivation of the organism. It would be destroyed on that raspberry. So it really depends on the food and it's ability to support good growth.
So for the most part, we are talking about refrigerated foods, because listeria is an organism that we refer to as a psychrotrophic organism, meaning that it can actually grow at temperatures as low as four degrees Celsius in your fridge. Just to give you some context, if you take something like salmonella, which everyone knows about, it can't grow at four degrees Celsius. So the strategies you have to put in place are very different from one organism to another.
