"In the last couple of years, wild boar have rapidly multiplied," a spokesman from the Environment Ministry told Spiegel Online. "Not only is there more corn being farmed, but warmer winters have also contributed to a boar boom."
The German Hunting Federation supports this claim. During the 2008/2009 hunting season, approximately 650,000 wild boar were shot, breaking previous records for such kills. Only 287,000 were shot the prior season, suggesting that fewer of these animals were around for the competitive hunters to target.
Wild boar remains a popular meat in Germany, where it's found in everything from stews to meatballs. Diners don't seem to be too deterred by the nuclear contamination scare, but the governmental reports on the meat aren't very appetizing. Spiegel mentions that Germany forbids anyone to sell meat containing high levels of radioactive caesium-137, meaning that animals with contamination levels of 600 becquerel per kilogram or higher must not be eaten. Some meat in Southern Germany has been measured at 7,000 becquerel per kilogram, however.
