According to a study published in the magazine Journal of Thrombosis and Haemostasis, taking into account that most of the unfractionated and low‐molecular‐weight heparins available worldwide are produced by Chinese companies from porcine mucosa and that the deadly African Swine Fever (ASF) outbreaks afflicting China since August 2018 may cause extensive losses to the pig herd, this can lead to serious consequences for the global supply of heparins.
