Can You Use a Meat Thermometer to Take Your Temperature?
Short answer: No. Please don’t. I’ve been running e-commerce stores for over 30 years, and every single year someone asks this question in customer service. Usually it’s 2 a.m., they’re feeling awful, the only thermometer in the house is the one they use for roast chicken, and Google has convinced them it’ll be “close enough.”
It won’t be close enough. And I’m going to tell you exactly why — from someone who has sold literally millions of thermometers (both kitchen and medical) and has seen every possible misuse imaginable.
Why People Even Ask This Question
It usually goes one of three ways:
- They’re sick, kids are screaming, it’s a holiday, every pharmacy is closed, and the Instant-Read they bought for Thanksgiving turkey is sitting right there on the counter.
- They saw some “life hack” TikTok or Reddit thread where someone stuck a ThermoPro in their mouth and lived to tell the tale.
- They’re cheap (been there myself in my broke 20s) and figure “a thermometer is a thermometer.”
I get it. I really do. But this is one of those corners you genuinely shouldn’t cut.
The Actual Differences (They’re Bigger Than You Think)
Meat thermometers and medical thermometers are not the same tool with different branding. They are built for completely different jobs.
| Feature | Meat Thermometer | Medical/Human Thermometer |
|---|---|---|
| Temperature Range | Usually -58°F to 572°F (-50°C to 300°C) | 89.6°F to 109.4°F (32°C to 43°C) |
| Accuracy in human range | ±2–4°F typical (sometimes worse) | ±0.2°F / ±0.1°C (clinical grade) |
| Probe length & sharpness | Long, sharp (to stab steaks) | Short, rounded, smooth |
| Response time | 2–10 seconds (optimized for thick meat) | 1–10 seconds depending on type (oral, ear, forehead) |
| Waterproofing | Often only splash-proof | Fully waterproof or disposable sheaths |
| Certification | None for medical use | FDA-cleared / CE medical device |
| Hygiene design | Can have crevices that trap meat juice | Designed for easy sterilization |
The biggest practical problem is accuracy in the narrow human range.
Your normal body temperature floats around 98.6°F (37°C). A fever starts getting serious above 100.4°F (38°C). A lot of meat thermometers are least accurate right around 95–105°F because that’s nowhere near the temperatures they’re designed to measure (165°F chicken, 203°F brisket, etc.). I’ve tested dozens of popular kitchen models in my warehouse with medical-grade water baths — many read 96.8°F when the bath is exactly 98.6°F. That’s enough to think you’re fine when you actually have a fever.
The Hygiene Issue Is Real
That probe that was inside a raw turkey last week? Yeah… even if you washed it with soap, there are microscopic pits in the metal where bacteria love to hide. Putting that in your mouth or your kid’s mouth is rolling the dice on salmonella or campylobacter just to avoid a $12 drugstore run.
“But I Saw It Work on YouTube!”
Sure. You can also start a fire with a chocolate bar and a soda can. Doesn’t make it the right tool.
In an absolute emergency (lost in the wilderness, whatever), yes, a meat thermometer will give you a rough idea if you’re hypothermic or burning up. But in 2025, with pharmacies, Amazon same-day, and decent medical thermometers costing less than a pizza, there is no real emergency that justifies it in everyday life.
What You Should Actually Buy Instead
After selling both categories for decades, here are my personal recommendations (and yes, these are the exact models we stock and ship thousands of every month):
Best budget option (< $15) → Classic digital oral/rectal/armpit thermometer (60-second reading, beeps, waterproof, last-reading memory). Boring, but literally bulletproof. Every parent should own one.
Best everyday upgrade ($20–30) → Non-contact infrared forehead thermometer. 1-second reading, no waking the sleeping sick kid, color fever indicator. We sell an absurd number of these.
Most accurate (hospital-grade, ~$80–120) → Ear (tympanic) thermometer from Braun or equivalent. The one doctors actually use in clinics.
If you really want one tool that does both meat AND humans decently There are a few ultra-high-end models (ThermoWorks Thermapen ONE, ~$140) that are accurate enough across both ranges, but they’re still not medically certified and the probe is too sharp/long for safe oral use. I own one. I use it for brisket, not my kids.
Bottom Line From Someone Who’s Sold Millions of These Things
Don’t use your meat thermometer on people. It’s not worth the risk, the inaccuracy, or the inevitable “why does my mouth taste like steak seasoning” moment.
Invest $12–$30 in a proper medical thermometer and sleep better knowing you’ll actually get a trustworthy reading when it matters most.
