“CooperSurgical 2 MHz Waterproof OB Probe Recalled for Incorrect Labeling.” GovInfoNow, updated September 17, 2026. https://govinfonow.com/recall/72900-coopersurgical-2-mhz-waterproof-ob-probe-recalled-for-incorrect-labeling. Based on FDA recall #Z-1131-2018 (https://api.fda.gov/device/enforcement.json?search=recall_number:%22Z-1131-2018%22&limit=1).

Why it’s dangerous

The probe was labeled incorrectly as a 3 MHz device when it is actually a 2 MHz device. This mismatch could cause inaccurate fetal heart rate readings during exams, potentially leading to incorrect pregnancy assessments. However, the risk is low as the probe is designed for specific obstetrical use cases.

Who’s affected

Pregnant women and healthcare providers using the probe for obstetrical exams. Women with larger body sizes may be at slightly higher risk due to the probe's intended use.

How to tell if you have this one

Check for the product name 'CooperSurgical 2 MHz Waterproof OB Probe' on the label. The recall covers probes sold with incorrect labeling as 3 MHz devices.
