In an update of its investigation last week, the FDA said it found that antiviral drug amantadine in some samples of imported chicken jerky treats sold a year or more ago, but doesn’t think it caused the illnesses. The FDA said it will continue to investigate.
Rival Petco announced on Tuesday that it would remove all Chinese-made treats from its 1,300 stores by the end of this year after shoppers pushed them to do so. The San Diego company said it has been cutting the number of those treats it sells over the past three years.
PetSmart Inc., which is based in Phoenix, owns more than 1,300 stores in North America.
