Phe La says it has recalled and stopped using plastic spoons previously promoted as reusable, according to VnExpress.
The October 18 report links the decision to questions about the material composition and earlier product claims.
Company's response
Phe La said its promotional descriptions had relied on documents, samples and test records supplied by the manufacturer.
The company stated that earlier testing had not separately established the material composition.
It said the supplier had described the product as meeting food-safety criteria. That is the company's account of the information it received, not a new independent finding announced by the report.
Phe La also asked customers to stop reusing the spoons.
Reporters observed replacement utensils at some Hanoi outlets, without the earlier environmental descriptions.
The business did not give a date for final verification results.
Material questions remain under review
The article says a customer arranged testing in late September and reported a polystyrene result.
That prompted questions about claims of reusability and biodegradability.
Material composition, the accuracy of advertising and any specific health effect are separate issues. The report does not establish an individual medical outcome.
It also does not announce a final regulatory determination of the whole case.
The confirmed new developments are the recall, changes at stores and continuing checks with the supplier. A complete account of the material verification remains dependent on further information.
