Precautions When Consuming Silkworm Pupae

BS.CKI Luu Xuan Dang, head of the Emergency Department at Lao Cai Provincial General Hospital, noted that while silkworm pupae are nutritious and delicious, consumers should be cautious to avoid food allergies and poisoning. Dr. Dang mentioned several cases of food poisoning caused by consuming silkworm pupae, with patients experiencing difficulty breathing and nausea, and emphasized the importance of seeking timely medical attention.

The causes of silkworm pupae poisoning vary. “It could be due to consuming stale pupae that have deteriorated, or the protein in the food has broken down and become toxic. Sometimes, chemicals are used to make the pupae look plumper and more appealing. It could also be an allergic reaction to peptides in the pupae or the sodium sulfite used as a preservative”, explained Dr. Dang.

Dr. Dang advised consumers to choose fresh silkworm pupae with a clear origin and avoid purchasing stale or suspicious-looking products. “Individuals with allergic tendencies should be especially cautious and consider refraining from consuming silkworm pupae and preservatives”, he added.

In case of any adverse reactions, such as difficulty breathing, nausea, whole-body itching, abdominal pain, cold sweats, or low blood pressure, Dr. Dang recommended seeking immediate medical attention at the nearest healthcare facility.
