As you will see from the below, prepared (ready-to-eat) foods and sprouts continue to be among the most risky items on the U.S. market. No amount of gourmet or health labelling guarantees safety.
Listeria monocytogenes bacteria, which pose a major threat to pregnant women, young children and people with a compromised immune system, are still very much a problem. Most recently this bacterium has cropped up in Snoqualmie Gourmet Ice Cream products (ice cream, gelato, custard and sorbet). It also turned up again in December in sprouts. Kkot Saem Sprouts, Inc. of Spanaway, Washington, had to recall its Soybean Sprouts and Mungbean Sprouts for this reason. In late November, soybean sprouts also had to be recalled by Henry’s Farm Inc. of Woodford, Virginia, because of Listeria.
Not surprisingly, this bacterium was also a suspect in prepared salads. Giant Eagle has issued a recall of Giant Eagle Apple Pistachio Salad and Apple Pistachio Salad with Chicken because of it. Global Garlic, Inc. of Miami, Florida, also had to recall a couple of its fresh curd products because it turned up. In addition, Acme Smoked Fish Corporation of Brooklyn, New York, had a nasty surprise when its imported (Product of Denmark) vacuum packs of Smoked Nova Salmon were found to be potentially contaminated with Listeria - another common location of the bacterium, particularly this time of the year.
Salmonella bacteria are also still present in our food, in spite of all the efforts to control them. During the past month for example, the company "Perfect Bar", had to issue a nationwide recall of large numbers of its Peanut Butter and Cranberry Crunch flavor nutrition bars due to potential contamination with Salmonella. And it has cropped up in cheeses too: Flat Creek Farm & Dairy of Swainsboro, Georgia, had to recall some of its Aztec Cheddar and Low Country Gouda. Another prepared food was also found to be contaminated: Overhill Farms, Inc. of Vernon, California had to recall its frozen Open Nature Chile Cheese Enchiladas due to potential Salmonella contamination.
So...not much has changed. Let's enjoy our great food, but be careful what we buy and eat, especially if we are in a high-risk category for getting sick.

We have a bad “holiday spoiler” food outbreak in the United States. It’s caramel apples. Several people have died, and many more are seriously ill. So far there is no actual recall, because we don’t know what brand of caramel apple is involved.
Here are the latest numbers from this food threat according to the CDC:
o Case Count: 28
o States: 10
o Deaths: 5
o Hospitalizations: 26
You’ll notice that there aren’t that many conclusively identified cases, but of these, a very high percentage ended up in hospital, and the death rate is also high.
The bacterium involved is Listeria once again. For those of you who have read the book (The Safe Food Handbook: How to Make Smart Choices about Risky Food), or who read this blog regularly, you will know that Listeria monocytogenes is often present in prepared foods – especially deli meats, sandwiches, salads, cheese and similar. This is the first case I can recall of it turning up in caramel apples.
Unfortunately, this tiny bacterium is a huge danger to pregnant women. Young children are also at more serious risk. In fact, in this case, nine of the serious illnesses were pregnancy-related (that is, they occurred in a pregnant woman or her newborn infant). Three of the very serious “invasive” cases were among otherwise healthy children, ages 5-15.
So what can we do to be safe? At the present time, the official CDC advice is for consumers to avoid all caramel apples – plain, with nuts, chocolate, sprinkles, or anything else. It could turn out to be one of the toppings, or the caramel itself. It seems that you can still keep eating caramels though. I am delighted that we don't need to give those up as well.
Investigators are hard at work trying to identify which ingredient in the caramel apples is contaminated, and the brand involved. I guess they won't have much time off this year.

Here are the real meanings of those freshness dates according to the U.S. Food and Drug Administration and the U.S. Department of Agriculture:
• A “Sell-By” date tells the store how long to display the product for sale.
• A “Best if Used By (or Before)” date is recommended for best flavor or quality. It is not a purchase or safety date.
• A “Use-By” date is the last date recommended for the use of the product while at peak quality.
So if these dates refer to quality, where does food safety come in at all? I would not dismiss the dates completely. After all, freshness does have something to do with safety as well as with quality. Personally, I use the dates in two ways.
First, when I am shopping, especially for products such as milk, eggs, meat, fish and so on, I always make sure I get the product with the latest date. You would be surprised at what a variety of dates there are for items such as milk on one shelf at a single store.
Secondly, I use the date as an indication of how long to keep the food. Yes, quality matters to me, but so does safety. No, I don’t always throw the item out as soon as it has reached the “use-by” date or the “best-by” date. Sometimes I keep it for a few more days. But I never rely exclusively on such dates. I also use the old-fashioned “look-and-sniff” approach as a guide.
If the food smells “off” even if the date says it shouldn’t, you may not want to take risks, especially if you are older, or have a suppressed immune system or are pregnant.

Symptoms of food poisoning can appear similar to those of Ebola in its early stages.
Here are the most common symptoms of Ebola (source: CDC): fever, severe headache, muscle pain, weakness, diarrhea, vomiting, abdominal (stomach) pain, unexplained hemorrhage (bleeding or bruising).
Now, let’s compare the most common symptoms of food poisoning caused by Norovirus – also called “stomach flu” although it is not related to influenza: fever, headache, other body aches, fatigue, diarrhea, vomiting, stomach pain. Notice that "unexplained hemorrhage" is not among the symptoms of Norovirus, but it is not present during the early stages of Ebola either.
Let’s take another common type of food poisoning, the one causes by various Salmonella bacteria, some more deadly than others. Common symptoms include: fever, headache, weakness, diarrhea, vomiting, abdominal cramps.
My point – unless you are in West Africa, have recently returned from West Africa where you might have been in contact with Ebola patients, or, have recently had close - and I mean VERY close - contact with an Ebola patient in another part of the world (not just shared a plane, but shared body fluids), relax! Those symptoms you are having could just be food poisoning (or, malaria, or some other nasty disease). But not Ebola.

Information about Ebola is changing from day to day, including the information coming from the experts. In the United States, the main “experts” are at the Centers for Disease Control and Prevention (CDC). I noticed today that they are now finally acknowledging breast milk as a route for Ebola transmission. They weren’t earlier. Maybe they have been reading the same research studies that I have been reading, especially some research done on earlier outbreaks of Ebola in Uganda.
What these studies show is that mothers who are infected with this virus can indeed pass on the virus to the infants they are breast feeding. But what the CDC does not mention as yet, is that research has apparently found that breast milk can carry the virus for weeks after the mother appears to have recovered.
Well, CDC, I think you had better make a correction on your website, especially in the paragraph which states:” Once someone recovers from Ebola, they can no longer spread the virus.” Not true….

The 2014 outbreak of Ebola is the worst one ever. It has become an international health emergency. At present the main outbreak is confined to West Africa, to Guinea, Liberia, and Sierra Leone, with a small number of cases cropping up in other countries, including in the United States and a few European nations. But everyone is afraid that it will spread further.
The total number of suspected cases of Ebola as of today is 9937 (actual lab confirmed cases are less). Deaths number 4877. These statistics have been updated on October 24, 2014. Assume that this is a huge underestimation: people are hiding the ill and often those who have died, and statistics in many of these countries are very poor anyway, particularly when it comes to reporting what happens in remote rural areas. I know, I have worked there.
Ebola, which used to be known as “Ebola hemorrhagic fever”, is a deadly disease caused by infection with one of the Ebola virus strains (see the photo above). Ebola is extremely contagious. It is transmitted from someone who is ill to another person by means of the sick person’s blood (for instance, through needle-sharing and through hospital equipment if shared or not properly sterilized) or through body fluids. Body fluids refer to urine, feces, vomit, semen, and saliva. Sweat can also transmit it under certain conditions. So far, the virus is believed not to be airborne, unlike many viruses.
Can you also catch Ebola from food? You will find most websites and media articles saying that you can't. But this type of transmission has been reported during previous outbreaks (for instance, in Uganda) when people in the more remote areas of Africa prepared or ate Ebola virus-contaminated "bushmeat" (such as monkey, bat ). Alright, people in most countries don't include "monkey tartare" or "bat sushi" on their diet (I have read, by the way, that bat soup can be delicious, though have never tried it). But can you catch Ebola from other kinds of food or drink as well?
In theory it is possible. When it comes to food or drink, the issue of saliva is important. Therefore, if you are in an area where there is Ebola, and especially if you are with someone who may have Ebola, you may want to be careful about drinking out of the same container (bottle, glass or whatever), sharing eating utensils, eating out of the same dish, or eating foods prepared or served by someone with Ebola symptoms, or, whom you don't know well. But let me add that the Ebola virus is a very fragile one, and is not believed to last long outside the body, so this type of transmission may be very rare. I don't even know if it has ever occurred in this or previous outbreaks. I have written to the Director of the United States Centers for Disease Control and Prevention (CDC) to ask. So far, no reply.
This is a later addition. Another, less direct route related to food has also occurred to me. I would assume that if the person serving your food and touching your glass or eating utensils is contagious, and sweats on them (as they well might if they are ill and running a temperature), then you might also be at risk for Ebola if this sweat enters a cut in your hand or you transfer the sweat to a mucous membrane. But this is just a hypothesis. No doubt, over the next few months we'll find out more.

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…..
