Every week, thousands of Mexicans cross the border into the U.S. on temporary visas to sell their blood plasma to profit-making pharmaceutical companies that lure them with Facebook ads and colorful flyers promising hefty cash rewards.
The donors, including some who say the payments are their only income, may take home up to $400 a month if they donate twice a week and earn various incentives, including “buddy bonuses” for recruiting friends or family. Unlike other nations that limit or forbid paid plasma donations at a high frequency out of concern for donor health and quality control, the U.S. allows companies to pay donors and has comparatively loose standards for monitoring their health.
U.S. Customs and Border Protection announced on June 15 that effective immediately, it would no longer permit Mexican citizens to cross into the U.S. on temporary visas to sell their blood plasma. A statement provided to ProPublica and ARD said that donating plasma is now considered “labor for hire,” which is illegal under the visitor visa most border residents use to cross into the United States to make donations.
A year after the U.S. barred Mexicans from crossing the border to sell their blood, pharmaceutical companies have acknowledged that those donations provided as much as 10% of the plasma collected nationwide as they seek to have the ban overturned.
Many US residents do sell their blood, but apparently not enough to meet the demand:
