Buyer beware: Those mummified remains might carry toxic spores

Those mummified human and animal remains are highly sought-after by collectors, but their acquisition may involve unregulated or even illegal trade practices. According to researchers, the risks to collectors extend beyond legal issues, as toxic substances used in the preservation process and microbial growth due to improper storage present significant health hazards.

The mummification process has often involved the use of toxic materials such as arsenic, mercury, and lead, necessitating careful handling to prevent adverse health effects. Professionals working with such remains typically wear protective gear like masks, gloves, and lab coats. Micro-organisms, including bacteria, fungi, and yeasts, can remain dormant in the tissues for centuries and recolonize, multiply, causing respiratory inflammation and infection if inhaled, as well as fever.

Past cases have revealed the presence of poisonous fungi spores that can cause adverse health effects, even in mummies stored in suboptimal conditions. Studies have found fungal growth on mummies displayed in museums and crypts, further highlighting the potential health risks.
