Breathalyzers are notoriously unrealiable:

There are 2 main possibilities
Alcohol containing product like mouthrinse may give you a false reading.
If you are diabetic, your breath contains acetones which will be picked up by a semiconductor breathalyzer, giving you a false positive.
Try getting a fuel cell breathalyzer like this one

I know that with most breathalyzers, the rule of thumb is to wait 20 minutes after drinking, eating, or smoking. As we all know, it takes about 20 minutes for alcohol to be absorbed into the bloodstream from the mouth. Therefore, it's a no-to wait 20 minutes on the drinking. But that doesn't explain the food phenomenom. Smoking can delay alcohol absorption, causing inaccurate BAC readings, and smoke particles blown into the breathalyzer can damage sensor also.
In addition, if food particles find their way into your breathalyzer it could also cause damage to the sensor or at least block your breath from reaching the sensor, causing an inaccurate reading.
