Crayfish—Paragonimiasis
Crayfish are ubiquitous in southern rivers and lakes, even thriving in rice paddies, ditches, and polluted waters. Their strong reproductive capacity makes them easy to catch.In recent years, spicy crayfish dishes have become wildly popular across China, with some regions even opening restaurants specializing in crayfish cuisine. However, since crayfish inhabit poor-quality water, they often carry lung flukes as parasites.
Consuming crayfish raw or undercooked poses a high risk of contracting this parasite, leading to lung fluke disease. The fluke primarily infests the human lungs. Mild cases may present as coughing, chest pain, or hemoptysis. Severe infections can cause massive pulmonary hemorrhage, obstructing organs and potentially resulting in death.Three Beijing residents once suffered life-threatening "acute rhabdomyolysis" after falling ill from eating crayfish.
Experts advise: Remove the tendon from the crayfish's back before eating. Ensure thorough cooking, and avoid consuming the head.
Sashimi -- Clonorchiasis
Fish fillets, deboned and sliced thinly, are dipped in wasabi and eaten raw for their exquisite flavor. Coated in batter and deep-fried, they become crispy yet tender. Yet while savoring such delicacies, the seeds of disaster may be swallowed whole. Freshwater fish like grass carp and flathead catfish often harbor liver flukes.
In regions like Guangdong and Guangxi, freshwater fish carry a parasite infection rate as high as 60%. Liver flukes primarily infest the bile ducts within the human liver, damaging the organ. Patients often experience liver pain, abdominal distension, and discomfort, with abnormal liver function detected during examinations.
Snails -- Guangzhou Strongyloides Infection
Strongyloides larvae develop over extended periods within certain terrestrial or aquatic snails. Some people, craving their tender flesh, consume them after merely blanching in boiling water. Eating raw or undercooked snail meat can lead to Strongyloides infection.
Once infected, the parasites migrate through the body, invading the brain. Lesions concentrate in brain tissue, affecting not only the cerebrum and meninges but also the cerebellum, brainstem, and spinal cord. Mild cases present with headaches, dizziness, nausea, and vomiting. Severe cases may lead to shock, delirium, or even death.Patients may develop eosinophilic meningoencephalitis or meningitis, characterized by a marked increase in eosinophils in the cerebrospinal fluid.
Water Chestnut - Clonorchis sinensis Infection
Autumn is the season for harvesting water chestnuts and Chinese water chestnuts. Freshly picked, they are tender and tempting to eat.However, consuming them at this time carries a high risk of infection from Clonorchis sinensis parasites present on the water chestnuts and water chestnuts. These parasites inhabit the human small intestine, causing digestive and systemic symptoms such as abdominal pain, bloating, and diarrhea. Severe cases may lead to anemia, edema, and developmental disorders.
Experts advise: Avoid eating water chestnuts, lotus roots, or water chestnuts raw, and never bite through their skins with your teeth. When consuming them raw, thoroughly scrub them clean. Boil them in hot water for several minutes or sun-dry them for a full day before eating. Practice good hygiene—never drink untreated water. Wash hands thoroughly after handling aquatic plants or contaminated water to prevent cysticercus contamination.
Can you eat oranges with worms?
While oranges infested with worms may look unsettling, the infestation is usually limited to specific segments. Simply remove the affected sections, and the rest of the fruit remains safe to eat.
Can you eat waxberries with worms?
Waxberries are highly nutritious and lack protective skin, making them a prime host for insect larvae. The small white worms found in waxberries are fly larvae. Since larvae are mostly protein, they pose no harm to humans. After purchasing fresh waxberries, soak them in a high-concentration saltwater solution for half an hour before consumption.
Can fermented tofu with worms be eaten?
The worms in fermented tofu are not fly maggots. Since they develop in a salty, vegetarian food, as long as the tofu wasn't produced in unsanitary conditions, these worms pose no significant health risk and are safe to consume.
This concludes our overview of foods most prone to carrying parasites. We hope this information has provided valuable insights. Wishing you good health and happiness!
