Since May, the Trump administration has paid a fledgling Texas company $7.3 million for test tubes needed in tracking the spread of the coronavirus nationwide. But, instead of the standard vials, Fillakit LLC has supplied plastic tubes made for bottling soda, which state health officials say are unusable.

The state officials say that these “preforms,” which are designed to be expanded with heat and pressure into 2-liter soda bottles, don’t fit the racks used in laboratory analysis of test samples. Even if the bottles were the right size, experts say, the company’s process likely contaminated the tubes and could yield false test results. Fillakit employees, some not wearing masks, gathered the miniature soda bottles with snow shovels and dumped them into plastic bins before squirting saline into them, all in the open air, according to former employees and ProPublica’s observation of the company’s operations.

“It wasn’t even clean, let alone sterile,” said Teresa Green, a retired science teacher who worked at Fillakit’s makeshift warehouse outside of Houston for two weeks before leaving out of frustration.
