The US Food and Drug Administration (FDA) is testing samples of Maggi, a Nestle instant noodle brand, which was recalled from stores across India last week, a spokeswoman for the Swiss food group said on Thursday.
Nestle, the world's largest food company, is seeking to defend its reputation in India after it pulled Maggi noodles from stores following reports by regulators that some packets contained excess lead.
A spokeswoman for the Swiss-based company said the United States' FDA was now also looking into the issue.
"We have been made aware that the FDA has taken samples of Maggi noodles manufactured in India from third-party importers' containers for testing, and we have asked the importers to advise us of the outcome of the FDA tests," the spokeswoman said in an emailed statement.
The FDA was not immediately available for comment. Nestle does not import, market or distribute Maggi noodles in the United States, the spokeswoman said.
Any Maggi noodle products in U.S. stores are sourced by retailers or imported through third parties, she added.
In a separate statement, Nestle India said it had lodged a judicial review with the Bombay High Court over an order from India's Food and Drug Administration, effectively seeking to clarify the state's method of testing the noodles.
