I’m a sucker for food safety jokes, and the punchline of “it must have been the Fukushima crabs” is a beauty.

According to the Telegraph, doctors in Russia who treated victims of a military test explosion have evidence of being exposed to radioactive materials, with isotopes being found within their muscle tissue.

Officials however are playing the food safety card when trying to explain why cesium-137 is there.

Staff from the Arkhangelsk regional hospital were not informed at first that they were treating irradiated patients, and protective measures were not taken until the next day, they told Russian media this week.

In some cases, staff said they were falsely told patients had been decontaminated.

One doctor was later found to have the isotope Caesium-137 in his muscle tissue. He was told he must have eaten too many “Fukushima crabs” during a trip to Thailand, his colleague told the news outlet Meduza.
