Macclesfield’s AstraZeneca plant is being investigated by US authorities, it emerged today.
The pharmaceutical giant issued a terse statement alongside its first quarter trading results.
The company said it had received a subpoena from the US Attorney’s Office in Boston, Massachusetts seeking documents and records related to “manufacturing, quality or good manufacturing practices at its Macclesfield facility”.
It added: “AstraZeneca is coordinating its response to the subpoena and intends to cooperate with the inquiry.”
The company recently announced the downsizing of its facility at Alderley Edge, moving most of the research work to Cambridge.
