The current SARS-CoV-2 pandemic demonstrated the potential risk posed by animal viruses
that are not primarily human pathogens. The high adaptability of some viruses reflected
by the spread to novel hosts is assisted by multiple factors directly or indirectly related
to human activities such as wildlife trade, ecosystem disruption, live-animal markets, exotic
food consumption, and intensified tourism. RNA viruses are very adaptable because of their
error-prone replication process and the likelihood of genetic recombination or reassortment
in some species. Even though, when compared to bacteria, food-borne virus transmission
is not the attention focus, it may represent a way of pathogen introduction to the human
population. Moreover, its relevance is enhanced considering that 75% of emerging infectious
agents are of zoonotic origin. This review focuses on the zoonotic food-borne transmission
of some viruses that may represent a risk for public health. Aside from the ability to... replicate
in the human GIT, the factors required for a virus to be transmissible via the zoonotic foodborne
route include its stability and the potential to infect various hosts. Most food processing
techniques are effective for virus inactivation, still, these are not applicable or performed for
some foods. For example, the hepatitis E virus infects pigs, wild boars, and deer and is transmitted
to humans through unprocessed meat. The Crimean-Congo hemorrhagic fever virus
is a tick-borne virus that occurs in ruminants, while humans can get infected by consuming
un-boiled milk and undercooked meat. Flaviviruses are mainly arthropod-borne, however,
there have been reports of their transmission via the food chain. Although unlikely, the possibility
of food-borne transmission for influenza A viruses has been studied and cannot be
dismissed. Some paramyxoviruses, also missing the common characteristics of food-borne
viruses can be transmitted by the contamination of certain foods with animal excretions. The
employment of the “One Health” concept, including constant epidemiological surveillance of
animals and improved reporting of disease occurrence in humans, would reduce the overall
risk of emerging viral diseases. Consistent application of hygienic measures is vital in facilities
where animals are raised, or in which animal products are processed and sold. Thus far, a limited number of identified zoonotic food-borne viruses has been recognized, and the potential
of certain viruses to be transmitted via this route should not be underestimated. Therefore, it
seems reasonable to constantly update our knowledge on this matter, thus creating the basis
for planning effective disease control strategies.
