Researchers at Laval University recently demonstrated that the herpes virus could remain infectious on food, drinks and surfaces associated with food for several hours.
In a press release released Wednesday, Laval University indicates that the study aimed to test the persistence of the virus Herpes simplex type 1 on surfaces such as stainless steel, aluminum, glass or plastic.
Tests were also carried out on cheddar cheese, sliced almonds, apple peel, orange juice, cola-type soft drink, coffee and milk.
Published in the Journal of Applied Microbiology in October, the conclusions of the study demonstrated that the herpes virus could survive at least 24 hours on all surfaces tested, and at least one hour on all foods.
Cola exception
The only exception, cola, probably due to its acidity
says the leader of the study, Julie Jean, professor at the Faculty of Agricultural and Food Sciences and researcher at the Institute on Nutrition and Functional Foods (INAF) from Laval University.
We also found that the virus was transferable from stainless steel to latex gloves, especially when they are wet
continues the professor. But not nitrile gloves.
Latex and nitrile gloves are those used by people working in the food industry, she says.
67% of the adult population carries the virus
The statement goes on to explain that, according to data from the World Health Organization (OMS), it is estimated that 67% of the adult population worldwide carries herpes virus type 1.
Our results show that foods and surfaces can potentially be involved in the transmission of this virus
adds Professor Julie Jean.
Although this transmission route has never been demonstrated in humans, our study constitutes a warning regarding the sharing of food and drinks.
She adds thatcaution must be exercised, especially if there are active lesions. Our observations also remind us of the importance of rigorously applying hygiene measures in the food industry.
