Colour me skeptical. That certainly doesn’t <i>sound</i> like a plausible number, and the article doesn’t cite any sources.<p>This article <a href="http://www.worldstopexports.com/top-blood-exporters-by-country/" rel="nofollow">http://www.worldstopexports.com/top-blood-exporters-by-count...</a> total US blood exports at $1.4 billion, a distant second to Ireland. That includes both human and animal blood, and I’m not sure what fractions human.<p>Soybean exports, on the other hand, are closer to $17 billion a year: <a href="https://www.ers.usda.gov/topics/international-markets-us-trade/us-agricultural-trade/outlook-for-us-agricultural-trade/" rel="nofollow">https://www.ers.usda.gov/topics/international-markets-us-tra...</a><p>Total US exports are $2.5 trillion, so blood is about 0.06% of that.<p>Edit: found a couple of reputable sources that put blood plus blood plasma exports in the $20 billion range. Possible that the discrepancy comes from whether plasma is included.
