If the frozen seafood nucleic acid tested by the customs is positive, can this product still be eaten?

Frozen seafood products have been tested positive for nucleic acid, so of course, such products should keep a certain distance from other products. In other words, it is better to stay away from this product. However, it is usually the outer packaging that detects that the frozen seafood is contaminated by COVID-19. If seafood can still be eaten, it can be eaten when cooked, but raw and cooked should be separated, and the hands that touch the outer packaging should be carefully washed.

If it is confirmed that a batch of frozen products are positive for nucleic acid detection and the contents are not contaminated, the external packaging can be disinfected. If the seafood itself is polluted, it is better to throw it away. Why risk a bite?

Novel coronavirus, previously found only in animals, invaded humans for the first time and caused pneumonia. We already know something about novel coronavirus, so let's briefly talk about this kind of novel coronavirus.

Novel coronavirus is a pathogen that mainly causes respiratory and intestinal diseases. This virus looks a bit like the emperor's crown, and there are many protrusions on the surface of the virus particles, so scientists named this virus? Coronavirus? . Coronavirus that infects humans has never invaded humans before, so what is the cause of this epidemic? Novel coronavirus? . This virus is not new, it is only the first time to infect people and make them sick.

Characteristics of novel coronavirus infection:

After people are infected with novel coronavirus, the clinical manifestations are mostly fever and fatigue, and the respiratory symptoms are mainly dry cough and dyspnea. Severe symptoms include acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, bleeding and coagulation dysfunction. Some patients have mild symptoms, may not have a fever, or even asymptomatic patients.

How to prevent novel coronavirus infection?

Although most people already know how to prevent it, it is still necessary to talk about how to prevent it when the global epidemic has not subsided.

1, wash your hands frequently

Pay special attention to hand hygiene. Many contact infections are transmitted by hand. Wash your hands carefully before, during and after preparing food, and wash your hands after going home; Wash your hands after sneezing or coughing; Wash your hands frequently when taking care of patients. In short, you should wash your hands carefully before touching your eyes, mouth, nose and food. Use soap and tap water for cleaning.

If it is inconvenient to wash your hands outside, you can wipe them with a wet towel containing alcohol or disinfect your hands with disposable disinfectant. Children, in particular, like to touch public facilities everywhere, so they must pay attention to their hand hygiene.

2. Keep your distance and avoid close contact.

The most effective way to prevent respiratory infectious diseases is to wear masks, keep a certain social distance, and avoid getting together, especially those who come back from epidemic areas, and avoid close contact during isolation.

3. Good eating habits

Try to eat cooked food, because many pathogenic bacteria are not resistant to high temperature, especially in novel coronavirus, which can be inactivated at 56 degrees Celsius for 30 minutes. Therefore, it is very safe to eat food after cooking. It is worth mentioning that freezing is not equal to sterilization. Many people think that freezing can freeze viruses, and frozen things are safer. In fact, this idea is very wrong, because many viruses are resistant to low temperature and can survive for many years at MINUS 60 degrees Celsius.

Some scholars believe that some viruses are ancient frozen viruses, and now the climate is warming and their activity is restored.

Therefore, if there is virus on the surface of frozen seafood, the surface can be disinfected. If you eat these seafood without knowing it, you should plan ahead and cook it before eating, which is relatively safe.
