Packaging of food is not a source of contamination, according to experts
Amid speculation that novel coronavirus disease (COVID-19) could spread through food, scientists have claimed that the same has not be established so far.
The World Health Organisation (WHO), in a situation report, noted that undercooked or raw meat should be avoided.
Studies are being conducted to evaluate the viability and survival time of SARS-CoV-2 virus. As a general rule, the consumption of raw or undercooked animal products should be avoided. Raw meat, raw milk or raw animal organs should be handled with care to avoid cross-contamination with uncooked foods.
Experts are of the view that even packaging of food is not a source of contamination.
“We don't have any evidence to prove that food or its packaging can get a person infected with COVID-19,” a media report quoted Benjamin Chapman, a professor and food safety specialist at North Carolina State University, as saying.
COVID-19 spreads from person-to-person through droplets when an infected person coughs or sneezes, or when she comes in contact with contaminated surfaces and then touches her nose, mouth or eyes.
Scientists believe that if food safety measures are in place, the spread of the disease is likely to be very less. Measures like washing hands frequently, cleaning surfaces, utensils and cooking food properly at the right temperature reduce chances of transmission through food. Even if the virus is present on food, or a person cooking food is infected, the chance of spread is low when these preventive measures are followed, according to experts.
Biologically, too, a virus cannot sustain on a surface for weeks and unlike bacteria, cannot grow on or inside food.
However, some viruses such as norovirus and rotavirus are known to cause foodborne illness. These viruses can, however, spread if the food is cleaned or processed with contaminated water.
For example, fruits and vegetables grown on land fertilised with animal waste or irrigated with contaminated water can have higher chances of carrying these viruses.
However, foodborne infections through norovirus and rotavirus can be prevented through good hygiene practices like washing hands, fruits, vegetables and meat products, according to scientists.
