Berkey Creamery, Penn State Favorite, Recalls Ice Cream And Frozen Yogurt Over Plastic Bits

Penn State has taken another rocky road. Its popular Berkey Creamery has recalled ice cream and frozen yogurt products because consumers found plastic pieces in them, according to reports (h/t MSN). One person even said there was a penny in a half-gallon.

The voluntary recall covers products manufactured between May 16 and Aug. 11, and consumers can return the ice cream in question for an exchange or a full refund, the Centre Daily Times reported. The "BEST IF USED BY" date on the products in question will be stamped between Feb. 10, 2013, and Aug. 11, 2013, the FDA wrote in a release.

No one has been hurt, and an investigation concluded that the tainting did not happen during manufacturing.

But as a precaution, NPR noted, the creamery is increasing its use of surveillance, and X-ray and metal detectors.

NPR reported that just three customers found plastic bits less than an inch long in Creamery half-gallons, yet the broad recall covers both the university campus and Internet sales. "Although by all accounts these appear to be isolated incidents, they are troubling to say the least," creamery manager Tom Palchak said in the FDA release.

The FDA added that the ice cream maker will switch to tamper-resistant packaging soon. touts the Creamery's "legendary status with Penn State alumni, local residents, and ice cream fans." It sells 25 to 30 flavors before Penn State football games. The Creamery is the largest university creamery in the country, its website boasts.
