Smart Lactation Pad Detects Acetaminophen in Breast Milk

By DairyNews7x7•Published on May 12, 2025

Researchers at the University of Southern California (USC) have developed a pioneering lactation pad equipped with real-time sensing technology to detect acetaminophen levels in breast milk. This innovation addresses concerns about the transfer of medications from lactating mothers to infants, particularly in regions where dairy products are fortified or derived from human milk sources.

Acetaminophen, commonly used by postpartum mothers for pain relief, can pass into breast milk, potentially affecting infants with underdeveloped livers. The smart lactation pad integrates electrodes and microfluidic channels into a standard pad, allowing it to sample breast milk naturally as it leaks. It then analyzes the milk for traces of acetaminophen without requiring any additional action from the mother. If the device detects acetaminophen levels that could be harmful to the baby, it alerts the user, enabling timely interventions.

This technology is particularly beneficial for mothers in remote or resource-limited areas, where access to laboratory testing is challenging. By providing immediate feedback, the device empowers mothers to make informed decisions about breastfeeding, ensuring the safety and well-being of their infants.

Industry Insight:

The development of this smart lactation pad signifies a significant advancement in ensuring the safety of dairy products derived from human milk. For the dairy industry, especially in sectors dealing with human milk-based products, this technology offers a tool to monitor and ensure the purity and safety of their offerings, aligning with global standards for infant nutrition and safety.
