READING, Pa.—Fifty-five piglets have been taken to an animal shelter after they were found left behind in a trailer on an eastern Pennsylvania highway median.

The Reading Eagle reports ( http://bit.ly/UIDfP7) the baby pigs were found left in a trailer on Route 222 in Bern Township on Wednesday afternoon. They've been taken to the Animal Rescue League of Berks County.

Officials say two of the trailer's wheels had been removed and it was sitting on the grass just south of an interchange. Construction workers called police when they saw that the trailer had been abandoned for several hours.

Police are now trying to track down their owner.
