A British archeological sponsor - Lord Carnarvon after attending the tombs opening died shortly afterwards inspiring supernatural “curse” speculation. • In recent years a scientific mummy's-curse theory was offered for Carnarvon's death. Was he killed by exposure to ancient, toxic pathogens from the sealed tomb? • Some ancient mummies do carry mold, including at least two potentially dangerous species—Aspergillus niger and Aspergillus flavus. • Some tomb walls may also be covered with respiratory- assaulting bacteria like Pseudomonas and Staphylococcus. • Bats inhabit many excavated tombs, and their droppings carry a fungus that can cause the influenza-like respiratory disease histoplasmosis. Under the right conditions such hazards could prove deadly. 66
  62. 62. Recommendations…. • If you suspect mold or mildew; or detect an unpleasant “musty” odor, there is usually excessive moisture, humidity or water present. Test the area. • Discovering the cause of, and remediating the source of the excessive moisture is essential to prevent a reoccurrence of mold. • Properly using the correct types of PPE is essential to safeguard your health. When in doubt, always proceed on the side of caution by making possibly dangerous situations non-issues. • Have resources “In Place” in Advance of a potential need. Conversely, developing a plan and searching for resources while under duress is far more stressful strategy that typically results in higher costs and longer recovery times. 67
