After this nuclear disaster, the sand in children's playgrounds in Germany was removed and replaced with uncontaminated sand to protect children who were most vulnerable to radioactivity. Some families temporarily left Germany to escape the fallout. Infant mortality increased significantly by 5% in 1987, the year after Chernobyl. In total, 316 more newborns died that year than statistically expected. In Germany, the caesium inventories from the Chernobyl nuclear disaster in soil and food decrease by 2-3% each year; however, the contamination of game and mushrooms was still comparatively high in 2015, especially in Bavaria; there are several cases of game meat, especially wild boar, exceeding the limits. However, controls are insufficient.
