UNHAPPY 25TH ANNIVERSARY, CHERNOBYL

Today is the 25th anniversary of the Chernobyl incident. On April 26, 1986, one of the reactors at the Chernobyl nuclear power facility (in what is now Ukraine) exploded. To remember, look at the photos on: http://www.boston.com/bigpicture/2011/04/chernobyl_disaster_25th_annive.html. They are very, very, moving - beautiful as well as tragic.

The World Health Organization (WHO) estimates that some 4,000 people have died from this accident (but others say this is a huge underestimation). The cost in terms of human suffering has been much higher.

In the wake of the more recent Fukushima disaster, a number of countries such as Germany, China and Switzerland, have re-assessed their nuclear power plans. Other nations are considering such moves. In the meantime, the leaks at Fukushima, continue to threaten the health of the population of Japan, not just through direct exposure, but through food and water.

CAN RICE BE CONTAMINATED?


We almost never hear of contaminated grains, including contaminated rice. But rice can be contaminated - like any other food. This can be a huge risk, since rice is the staple food for about half the world. Children, as well as adults, may eat large amounts of it regularly, particularly if they are poor and can afford little else. Or, you may be well off, but be more exposed to risks in rice if you go on one of the rice diets to lose weight, as a friend of mine did.

Many of the nastier things that have cropped up in rice have been absorbed into the rice from the soil they grow in. In Japan, it's now rice planting time, and the government has issued restrictions about planting in some areas affected by radiation from the Fukushima power plant, because of fears that the rice will pick up the radioisotope cesium-137 from the soil. It's sad for the rice farmers but good that care is being taken to keep the food supply safe.

But radiation is not the only hazard that rice can pick up. When I was doing the research for The Safe Food Handbook, one of the issues I became most absorbed in, and contacted top researchers world wide, was the risk of arsenic in rice. As we know, arsenic is one of the worst heavy metals. It can be present in soil, as when arsenic-based presitcides have been used on previous crops such as cotton, to control the boll weevel. Certain plants absorb arsenic, others do not. Rice is one that does.

Quite high levels of arsenic have indeed been found in rice from certain parts of south-central United States, and in some - not all - rice from countries such as Bangaldesh and India. Organic growing conditions will not guarantee that the rice will be low in arsenic, as it can stay there for very long periods of time.

These are just two possible contaminants in rice. And wouldn't it - brown rice, and especially rice bran, are likely to be more risky. Nutrition and food safety do not always agree.

CONTAMINATED SPINACH AND MILK NEAR JAPAN'S NUCLEAR PLANT

It was simply a matter of time. As I have been arguing for the past few days, the spread of fairly high levels of radiation in Japan will contaminate growing food. And, I said that the experience of Chernobyl suggested that vegetables like leafy greens and milk would be first to be affected. I was right.



Today Associated Press, Reuters and other news sources reported that the levels of radiation contamination found in spinach and milk on farms near the affected nuclear plant (some as far as 60 miles away) now exceed government safety levels. Further tests are being done and shipments of food from the area may be stopped and people advised not to eat them.

If that does happen, the same thing could occur as did after the Chernobyl: the food will be sold informally and eaten locally anyway, in spite of government warnings. Why? Because there is food scarcity in many disaster-affected places. People who are faced with a choice between hunger and the risk of a little toxic food, will often opt for the latter.

The good news is that a few meals will be unlikely to affect them. But eating it over a period of time - say a year - could do so, especially in the case of children, and with people also exposed to radiation directly.
