Counterfeit coronavirus tests were intercepted at Chicago’s O’Hare International Airport this week, US Customs and Border Protection officials said Thursday.

The kits, shipped from the United Kingdom, included tests for COVID-19, as well as other illnesses, including meningitis and salmonella, officials said.

They were seized on Tuesday and handed to the FDA for further analysis.

“Counterfeit products have serious consequences to everyone,” Hans Leiterman, assistant area port director for Chicago said in a statement.

“CBP seizures of illegally imported counterfeit merchandise helps protect the health and safety of US citizens, and the reputation of marketplaces involved in these transactions.”

The federal agency warned that testing for the coronavirus should only be conducted by approved state or local public health laboratories.
