Casimir IV's Tomb

After opening the tomb of Casimir IV of Lithuania and Poland in 1973, four of the 12 people present died within a few days, and six more soon afterwards. During later examinations, a microbiologist found traces of fungi on the royal insignia taken from the tomb. He identified three species: Aspergillus flavus, Penicillium rubrum, and Penicillium rugulosum. These fungi are known to produce aflatoxins that can be deadly when in contact with the skin and inhaled into the lungs.
