Mercury Fever Thermometers & Thermostats
The Issue
Older fever thermometers and thermostats contain mercury which is a potent neurotoxin that bio-accumulates in human and fish tissue and poses a public health and environmental threat. Old fashioned mercury thermometers and thermostats can no longer be disposed of in the trash. For this reason, extra care must be taken when handling a mercury thermometer and thermostat.

How do you know if your fever thermometer contains mercury? It has a silver stream.

What You Can Do
Never dispose of mercury or mercury containing materials down the drain or in the garbage.

If you are replacing a mercury thermostat, make sure to recycle it. You can recycle your mercury thermostats and thermometers for free through the County of Santa Clara Household Hazardous Waste Program.
