Researchers at Canada’s Laval University have shown that herpes type 1 – that is, the virus that causes oral herpes – can persist for about an hour on food.
According to the information that the authors of this study give in the Journal de Montreal, they evaluated the persistence of the virus on cheese, almonds, apple peel, orange juice, milk and a carbonated drink.
The results show that food, including some surfaces, may be involved in the transmission of the virus.
“Although this way of transmission has never been demonstrated in humans, here, our study represents a warning regarding the risk of contamination with this virus through food and some drinks”, explains the research coordinator, Julie Jean, professor at the Faculty of agricultural and food sciences.
And he adds: We also evaluated the transfer of the virus from a stainless steel surface and from latex or nitrile gloves used by people in the food industry.
Thus, the researchers identified the virus on certain surfaces: stainless steel, aluminum, glass, plastic. Interestingly, the researchers did not observe the virus in cola, “probably because of the acidity” of this drink.
Data from the World Health Organization show that more than 3.7 billion people under the age of 50 are infected with herpes simplex virus type 1 (HSV-1). This virus can cause oral herpes. This infection is cured, but the virus persists in the body even after healing. It settles in the sensitive nerve ganglia and, in case of low immunity, the virus can reactivate.
