There are some speculations now that the Heparin contamination was intentional and done deliberately for the 13 countries that received the contaminated Heparin. This is a shocking revelation and will scare people from buying products from countries that are not really friends. In a way, deliberate contamination is an act of war against innocent citizens of another country.
This is similar to cops never buying food that they cannot see visually being prepared. The juvelines at the counter have typically encountered cops before and they see the food preparation as an opportunity to pass on some body fluids to the cops. This makes cops a great fan of doughnuts, Subway and Quiznos.
So China has a lot of explaining to do now. I wonder how many such abuses happen with other food items and medicines that come from other countries.
