Can anyone recommend a laboratory in the U.S. that can help identify the source of foreign objects such as plastic bags? Also, can anyone recommend a type of x-ray machine or detection device that can be put on a manufacturing line as is a metal detector, and reliably detect blastic bag contamination. We have had three different complaints this year for various plastic bag contamination events, two of which were from our process, so I'm looking for a long term solution. We can't use a sieve because we need the finished product to contain chunks of fruit, so we don't want to sieve out the fruit chunks.
Any suggestions are helpful.
