Candling, the traditional means of detecting parasites during fish fillet processing, is time consuming and labor intensive. This method is a major factor in reducing the quality and increasing the cost of fish brought to market. The difference in electrical conductivity between fish and an embedded parasite was hypothesized to be a practical basis for an instrument which would have potential for automated parasite detection. A small electrical current was passed through a parasite‐containing fillet and the magnetic field above the fillet was recorded by a Superconducting Quantum Interference Device magnetometer. Results indicate potentially successful detection of parasites by the device.
