This should be a pretty short post.
While I think that the press does an okay job, sometimes it's what they don't say or explain that can really get you into trouble. That's what happened to a friend of mine and a text message to me trying to get to the real skinny on what happened as follows:
It's the recent story about how wine from California bottled sometime after the Fukushima event of 2011 came to have been found to have greater levels of a radioactive isotope called Cesium-137. Researchers found that they could determine what effects, if any, the event may have had by a means by which they could measure this Cesium-137 in the bottle.
They did find increased levels in two grapes that were specifically targeted, Cabernet Sauvignon and a Grenache Rosé. To shorten things up, I've attached the Wine Spectator article that you can read by clicking here. Short version, miniscule heightened levels were detected.
Here's the part they didn't tell you. IF there was a radioactive cloud that came over the Western United States, and potentially elsewhere, it would have deposited this heightened level of Cesium-137 on ALL crops of ANY type, not just wine. The ONLY way these researchers could check their assumptions was to find a product that would still be around right after 2011. Most fruits and produce of that time have been picked, eaten, digested and returned to the soil, so to speak. What's left? WINE! So wine was used because bottles from that time period were still around and could be used in the research.
While I can't remember that far back, I don't seem to recall the press mentioning this radioactive cloud thing back then, I may be wrong...
To try and be fair, a couple of articles I read did mention that the levels were not high enough to worry about. One also mentioned that after Fukushima, and off Japan's coast, fish were contaminated and unsafe to eat.
So drink away, well to your normal proclivity (snuck that word of the day in), and enjoy.
