Soft plastic is perhaps the most common food contaminant, but it is also one of the most challenging to detect. Failure to remove it can present serious safety risks for the consumer, which is clearly something every food manufacturer wants to avoid. In the fruit processing industry, fragments from fruit stones are a constant concern. With their sharp edges, these contaminants can potentially cause the same damage as fragments of glass. Other common threats include wood splinters from pallets, hard plastics from processing equipment, and rubber from broken gaskets.
