The Biohazard Risks of Human Tissue Keepsakes and Placentophagy

The practice of retaining human tissue—ranging from the common tradition of saving baby teeth to the more controversial trends of placentophagy and jewelry made from surgical remains—is creating a complex intersection of personal autonomy, cultural ritual, and significant public health risk. While the emotional impetus behind these keepsakes is often rooted in a desire to commemorate life milestones or medical triumphs, the clinical reality is fraught with biohazard concerns that the medical community is increasingly forced to address. As these practices move from the fringe into the mainstream wellness space, the lack of standardized regulatory oversight poses a growing challenge for healthcare providers and public health officials alike.

One of the most prominent and debated aspects of this trend is placentophagy, the consumption of the placenta after childbirth. Proponents often claim it can prevent postpartum depression, improve milk production, and replenish nutrients. However, clinical evidence supporting these claims remains virtually non-existent. From a pharmacological and toxicological perspective, the placenta functions as a filter during pregnancy, potentially accumulating heavy metals like cadmium, lead, and mercury. Furthermore, the process of encapsulating the placenta—dehydrating and grinding it into pills—is often performed by unregulated third parties. This lack of sterilization standards has led to documented cases of neonatal sepsis, most notably a 2017 CDC report where a newborn contracted late-onset Group B Streptococcus (GBS) after the mother consumed infected placenta capsules.

Beyond consumption, the retention of surgical remains, such as gallstones, prosthetic hardware, or even excised bone like kneecaps, presents a different set of logistical and safety hurdles. Hospitals generally treat excised human tissue as pathological waste, subject to strict biohazard disposal protocols. When a patient requests to keep a part of their body, they are essentially asking to take home a potential vector for bloodborne pathogens. Formaldehyde, often used to preserve such specimens, is a known carcinogen and poses its own handling risks in a domestic setting. Without professional preservation, organic tissue undergoes rapid decomposition, leading to bacterial growth and foul odors, which can create health hazards in the home.
