Over the past couple of decades, food processors increasingly have come to rely on X-ray inspection equipment to detect physical contaminants during production. This is not surprising because X-ray inspection equipment has become more sensitive, more affordable and more reliable. X-ray systems can also be very intuitive and easy to use.
Still, some food manufacturers have lingering worries about the safety of X-ray technology – both for those operating the equipment and the food products the machines inspect.
The bottom line: X-ray inspection of packaged and bulk food product is proven to be extremely safe.
There is no documented evidence of adverse health effects of X-rays on equipment operators, the food products that travel through the equipment and ultimately the consumer of those products.
To understand why this is true, let’s take a close look at how today’s X-ray inspection equipment works and correct any misconceptions associated with this commonly used technology.
