Frequently Asked Questions

Why should I use the hand scanner?
The PathSpot hand scanners detect invisible signs of foodborne illness that could make your customers sick. By scanning every time you wash your hands, you can help protect your team and your customers from foodborne illness.

How do I use it?
After you have thoroughly washed and dried your hands, place them under the hand scanner. Your hands will trigger a light to shine on your hands. Follow the instructions on the screen.

How often should I scan?
You should scan every time you wash your hands to confirm your hands are safe to handle food.

What does it detect?
The PathSpot hand scanner looks for specific indicators of dangerous bacteria and viruses that cause foodborne illness including E-Coli, Norovirus, Salmonella, Listeria, and Hepatitis A.

Does it use UV rays that could be dangerous?
No, the light is not dangerous. The color of the light used during the scan is in the visible spectrum, it does not use UV rays and it does not emit UV radiation.

Why did I pass the scan if my hands are ‘dirty’?
The PathSpot hand scanner is not designed to detect dirt, germs, food scraps or other contaminants. It is designed to detect specific indicators of bacteria and viruses that cause foodborne illness.

Do the hand scanners replace handwashing?
No. Team members must wash their hands even if the scan does not detect signs of foodborne illness. The scan does not look for germs, dirt, the flu, or other dangerous materials that could contaminate food.

Do I need to scan even if I wear gloves?
Yes. You should scan your hands every time you wash your hands, whether or not your team wears gloves.

What do I do if an indicator of foodborne illness is detected?
This is a good thing because together we’ve identified a sign of foodborne illness before you handled food and before anyone got sick. Simply rewash your hands and scan again within 2 minutes.

How long does the scan take?
Only 2 seconds!

How does the technology work?
The PathSpot hand scanner uses a technology called “visible light fluorescence spectroscopy” to detect indicators of viruses and bacteria that cause foodborne illness, including E-Coli, Norovirus, Salmonella, Listeria, Hepatitis A. It measures the reflection of light off your hands to determine whether or not a set of proprietary markers are present.

Who sees the data from the hand scanners?
General Managers, Regional Managers, and other food safety stakeholders in your organization can access the data. Together, your team can use the data to confirm proper frequency and effectiveness of handwashing practices and to protect against foodborne illness. The PathSpot team will regularly monitor the data to confirm that everything is running smoothly. PathSpot Support will notify the General Manager if a team member fails to rewash and rescan their hands after a sign of foodborne illness is detected.

What do I do if the device is not functioning properly?
Please see the Troubleshooting section of the General Manager Manual, and if the problem does not resolve, email PathSpot Support at
