The H5N1 virus, responsible for avian flu, has been identified in pasteurized cow's milk in the United States, raising concerns about a possible resurgence of the epizootic. The World Health Organization (WHO) has called for strengthening detection of the virus, capable of infecting many animal species.
A case of human infection was reported in Texas after direct contact with a cow. The virus can infect humans in two specific places: the conjunctiva of the eye, causing a mild infection, or the pulmonary alveolus, which can cause a serious infection. Of around 900 cases of human H5N1 infection recorded by the WHO over the past twenty years, half were fatal.
However, consuming pasteurized milk, even containing traces of the virus, does not present a risk, as pasteurization has destroyed the virus. In France, no risk has been demonstrated with the consumption of unpasteurized milk contaminated with H5N1.
The strain of the virus currently present in the United States differs from those in Europe. In addition, there is no circulation of this virus among French cattle. According to scientists, despite increased vigilance, consumers should not worry.
