HEALTHY DIRT IN FOOD?

Today's editorial by Jeff Leach in the New York Times - title: " Dirtying up Our Diets" - makes some useful points. Yes, the good bacteria in our gut play an important role in protecting us from the bad ones. Yes, antibiotics are overprescribed and tend to wipe them out.

But no, America does not have "the safest food supply in human history." I would argue that that honor goes to some European countries instead. And no, we cannot cure our autoimmune disease issues by eating Farmers Market food.

Really! Does Leach think that most of us never wash our Farmers Markets carrots, but eat them dirt and all? I would bet most of us triple washed them, and if we can't get that dirt off, then we scrub them. I mean, who wants to crunch on soil? If you have ever done it, you don't want to do it again.

And, if you want bacteria, you may well get a worse dose from those squaky clean, triple-washed, safe-to-eat, bagged greens and other produce. But of course, it will not be the kind of nice safe bacteria that your gut needs.

IS ORGANIC FOOD MORE DANGEROUS?

I am always surprised by the number of people who believe that if a food item is "organic" it will not carry any bad bacteria. Yes, organic fruits or vegetables are likely to have lower levels of pesticides. But that does not protect them from those dangerous bacteria that we hear so much about these days - ones such as E.coli 0157, Salmonella, Listeria monocytogenes and others. In fact, much of the research done suggests that they are even more likely to be contaminated than are conventionally grown foods.

The Rocky Ford cantaloupes that are causing the current outbreak of Listeriosis (from Listeria monocytogenes bacteria) were "pesticide free." (They have now caused at least 22 deaths and over 100 illnesses). The recently recalled grape tomatoes were organic.

Over the past few years we have had recalls of a huge range of organic foods because they were contaminated - including organic alfalfa sprouts, many organic fruits and vegetables, organic beef, organic turkey, organic peanut butter, organic eggs, organic cheese and even of organic chocolate and tea. (What have I missed?)

In fact, sad though it be, several recent studies, including one published this past May in the Journal of Food Protection, have concluded that organic food is more likely to have fecal contamination which is where these bacteria usually come from. The higher incidences of fecal contamination in organic foods is linked to the heavy reliance of composted animal manure for fertilizer. The book discusses this issue in more detail.

AVOIDING RADIATION IN FOOD IN JAPAN

It is now more than 6 months since the tragic earthquake, tsunami and massive damage to the Daiichi nuclear power plant in Fukushima, Japan. Although it is largely out of the international news these days, the difficulties in Japan continue. A major concern for many people is safety of their own and their family's food. How can they make sure it doesn't carry too much radiation, and endanger their health?

Unfortunately - as I predicted in early March (see earlier posts) - radionuclides are indeed turning up in Japan's food at high levels - often many times the safety standards established. Dangerous levels of radiation have now been found in such foods as beef, plums, spinach, bamboo shoots, rice, tea, milk, seaweed and fish. Some of this radiation-contaminated food has come from as far away as 360 kilometers from the nuclear plant.
Yes, authorities in Fukushima and neighboring prefectures are conducting spot checks on a growing number of food products. But clearly, as in any such activity, some is caught and some is missed. It is impossible to check every food item.

Effective controls also depend on cooperation of farmers, and farmers are understandably concerned about how positive findings would affect their livelihoods.

Many consumers are convinced that the government is just not doing enough to keep them safe. Rightly so, mothers of young children, pregnant and lactating women, are particularly concerned. Some strategies people are using themselves to try to avoid the more contaminated food products include:

• Avoiding foods from certain prefectures. But this is not as easy to do as one might assume.
• Joining cooperatives which re-test the food products they sell. But there is a price mark-up to cover the cost of such testing, which excludes people who are not as well off.
• Buying canned or frozen or dried products which were packaged prior to March, 2011.
• Diversification: for instance, rotating the brand of milk they buy so that their risks are reduced from any single one.
• Avoiding certain fresh food items altogether which they feel might be more likely to be contaminated, such as leafy greens, fresh milk.
• Eating imported foods as much as possible.

A few meals of food with high radiation levels are unlikely to hurt most people. But eating such food regularly over a period of time, has been shown by research to increase certain cancer risks as well as lead to other health problems, particularly if you are also being exposed to such contaminants from other sources (such as your water, or the environment). Yes, it is a good idea to be careful.

IS THERE TOO MUCH RADIATION IN RICE?

This blog warned about nuclear contamination of food in Japan very soon after the Fukushima nuclear plant crisis in northeast Japan on March 11. At that point, there was, as yet, no evidence or discussion of it. (Read the 20 earlier posts on this issue, beginning March 15). These fears have been confirmed. Excessive levels of radiation have been found in milk, vegetables, fruit, seaweed, fish, drinking water, animal feed - and, most recently, in beef.

It was only a matter of time before attention would turn to rice. Back on April 10, I (see "Can Rice be Contaminated?") I mentioned that the Government of Japan had advised farmers not to plant rice in certain areas because of this risk. We'll know soon whether such warnings were enough. The rice planted back in the spring is about to be harvested. Government-required testing of the rice is beginning in at least 14 prefectures in north and east Japan. About 40 percent of the annually harvested over 8 million tons of rice is grown in this area.

The testing will check levels of cesium in rice to make sure that they are not above the maximum government-imposed cap of 500 becquerels per kilogram. If any are, then shipments of rice from the area will be stopped.

Obviously farmers are anxious. But so are consumers. Rice is something that most people in Japan eat every day - including young children and pregnant women, who are at special risk. Cesium can build up in the body, resulting in higher risk for certain cancers as well as other health problems.
