Manufacturer Protica Inc. said Wednesday it is recalling some dietary supplements sold in the United States and Canada because utility knife blades were found in two vials of the products. No injuries were reported.

The source of blades is unknown and both U.S. and Canadian authorities are investigating the suspected tampering, said James Duffy, founder and president of Protica, based in Whitehall, Pa.

Protica manufactured the supplements for two companies, which sold the test tube-like vials under their own private labels.

One blade was found in a vial of Hardcore Energize Bullet, made for iSatori Technologies of Golden, Colo. The Hardcore Energize Bullet vials included in the recall were sold in Canada.

Another blade was found in a vial of New Whey, which Protica makes for IDS of Oviedo, Fla. The vials s included in the recall were sold in the United States.

The caps of the tampered vials did not include the best-by date and lot code information ordinarily featured on each container.

The Food and Drug Administration warned consumers not to use the dietary supplements. Its Office of Criminal Investigation is probing the suspected tampering, as are Canadian authorities.

Vials affected by the recall can be returned to the place where they were purchased for a full refund. For details, call 800-776-8422.
