Many of us look forward to that time of year when we can get fresh stone fruit such as peaches, plums and nectarines. But this year some people living in the United States are having second thoughts about eating these stone fruit. Why? Because of a widespread recall of peaches, nectarines, pluots, and plums due to fear that they may be contaminated with Listeria monocytogenes, a very dangerous bacterium.
The fruit being recalled was distributed by California-based Wawona Packing Company, to many of the large retail chains in the U.S, such as Costco, Trader Joe's, Walmart, Kroger and Sam's Club. It was also used in several baked goods which are now being recalled as well.
So what do you do if you recently bought such fruit? Well, one way to deal with the problem – particularly if you are in a high risk group for Listeriosis (pregnant women, elderly, people with severe health problems) is to thoroughly cook the fruit, which will kill any bacteria in it.
In fact, right now I have several pounds of peaches sitting in my refrigerator that we are not eating raw. They are probably safe, as my handyman gave them to me, and he had picked them right off the tree himself. But it is best to be careful, so I have decided to make them into peach crumble and peach jam and chutney. As for the plums we eat, they either come from our own 6 plum trees or that of our neighbor’s, so I am not concerned.
But how can healthy fruit pose such a risk to our health? The problem is that bacteria are everywhere – in the soil, in water used for irrigation and for post-harvest washing of fruit, and in the packing plant. Actually, we don’t know much about how and why the Listeria monocytogens bacterium enters fruit (or vegetables). Research suggests that while it could enter during growth, from the soil, fertilizer used, or the water, it is more likely to occur post-harvest, during cutting or shredding of fruit, or, if the fruit is damaged. Differences in the temperature of the fruit and the water it is washed with may also be a factor.
More and more of us are eating raw fruit and vegetables. But, as pointed out by The Safe Food Handbook: How to Make Safe Choices about Risky Food, (the book – not this blog), unfortunately fresh fruit and vegetables are a very common source of food poisoning. So here we go again…..
To your good health,
