Three individuals in China have been identified with a bacterial infection allegedly from consuming cooked sheep placenta, which they believed to be nutritious.
In southern China's Guangdong province, a woman named Zhang was hospitalized after consuming cooked sheep placenta, a practice known in Traditional Chinese Medicine (TCM) as ziheche. The consumption of this "tonic" led to the diagnosis of brucellosis in Zhang, her sister, and brother-in-law, a type of bacterial infection that can be spread from animals to humans.
The event has sparked an online discussion about the custom of consuming sheep placenta in China. While the placenta is believed to address infertility issues, boost the immune system, treat fatigue, and combat a lack of energy, evidence suggests that consuming it carries significant risks.
One of the key potential health risks is the transmission of hemotropic bacteria such as Anaplasma spp., Mycoplasma spp., and protozoa, which can survive in placental tissue and pose a risk of transmission if the placenta is consumed without proper sterilization or preparation [1].
Moreover, the placenta can harbor various pathogens known to cause abortions or fetal developmental abnormalities, such as Rift Valley fever virus and Toxoplasma gondii, though these are more commonly studied in veterinary medicine [4][5]. This adds an additional layer of concern regarding placental consumption beyond traditional beliefs.
Exposure to such pathogens could lead to zoonotic infections or trigger immune or allergic reactions due to biological contaminants. The potential health risks associated with consuming sheep placenta in TCM primarily stem from the risk of infection by pathogens present in sheep placental tissue.
The case of Zhang and her family likely illustrates an instance where consumption led to adverse health outcomes tied to such infections. However, no direct detailed clinical case of Zhang and her family was found in the search results.
It is crucial to exercise caution when using animal placenta in TCM medicinal practices. Sourcing, sterilization, and preparation should be carried out with the utmost care to minimize the risks associated with pathogen transmission.

Health-and-wellness experts caution against the practice of consuming sheep placenta, as evidenced in Traditional Chinese Medicine (TCM), due to the potential risks associated with pathogen transmission, such as those posed by hemotropic bacteria, Rift Valley fever virus, and Toxoplasma gondii. Instead, following a balanced diet with a focus on nutrition and healthy diets could contribute more positively to overall health and wellness.
