Coronavirus test kits that were to be sent to the United Kingdom were found to be contaminated with COVID-19, The Telegraph reports.
This comes at a time when the UK is ramping up efforts to boost testing in the country. The country has reached out to private companies to help make tests.
Luxembourg-based manufacturer Eurofins told UK officials that deliveries would be delayed because core parts were contaminated with the virus.
The delay is not expected to significantly impact the country’s testing for the virus.
The news comes after days of confusion over how much testing the UK is doing.
Cabinet minister Michael Gove said on Sunday that the UK had met its target for this stage of the coronavirus response with 10,000 tests done that day.
Meanwhile a former director of the World Health Organisation has criticised the UK’s testing efforts .
Professor Anthony Costello, who now works at University College London, told BBC Radio 4’s Today programme that the UK isn’t using its resources as efficiently as countries like Germany – which is doing 70,000 tests per day.
He said: “We have 44 molecular virology labs in the UK. If they were doing 400 tests a day we would be up to Germany levels of testing and that is perfectly feasible…
“If you look at Korea, they have done 490,000 tests. Their death rate is three per million and they have suppressed the virus.
“I don’t see why we can’t get these 44 labs up and running, finding cases and testing.
“We must go to mass testing and when we remove the lockdown… then we will have a control mechanism which will enable us to wait, without socially distancing the whole country, for drugs or a vaccine for herd immunity.
