¿Por qué existe un fenómeno de transmisión de alimentos/bienes de la cadena de frío??

Luan Rongsheng: Alimentos de cadena de frío significa que después de que los alimentos perecederos se compran o capturan en el lugar de origen, Todos los enlaces deben estar en un ambiente de baja temperatura durante el procesamiento del producto., almacenamiento, transportación, distribución y venta minorista hasta llegar a los consumidores.

¿Y por qué hay un fenómeno de transmisión de alimentos/bienes de la cadena de frío?? Because frozen food itself is in a low temperature state, if it is contaminated, the virus will survive for a long time. en segundo lugar, in the place where frozen food is processed, the temperature is low and the space is closed. If there is a source of infection in the processing place at this time, it will cause human-to-human transmission or human-to-human transmission. There are more sources of infection, so the probability of cold chain food being polluted is greater.

Esto podría deberse a una infección asintomática., unlike cold chain foods, fruits can’t be frozen for a long time or not. Además, the environment in which they live is ventilated, and the temperature is higher than that of cold chain foods, and viruses can’t survive on the surface of fruits for too long, so it is unlikely that viruses exist on the surface of fruits. Actualmente, there are no cases of infection caused by eating fruits, so the risk is extremely low. Además, most viruses on the surface of fruits can be removed by washing with clear water.

Además, the person-to-person transmission of cold chain food is not the infected person who eats the cold chain food, but spread through contact. Es decir, other body parts such as hands come into contact with contaminated frozen food or contaminated packaging, and then touch the mouth, eyes and nose with hands, thus being infected. Es más, it can be spread by contact, and it is also exposed to large droplets with high concentration and contaminated frozen food/articles with high concentration.
