Validation of modified radio-frequency identification tag firmware, using an equine population case study.
Abstract: Contact networks can be used to assess disease spread potential within a population. However, the data required to generate the networks can be challenging to collect. One method of collecting this type of data is by using radio-frequency identification (RFID) tags. The OpenBeacon RFID system generally consists of tags and readers. Communicating tags should be within 10m of the readers, which are powered by an external power source. The readers are challenging to implement in agricultural settings due to the lack of a power source and the large area needed to be covered. OpenBeacon firmware was modified to use the tag's onboard flash memory for data storage. The tags were deployed within an equine facility for a 7-day period. Tags were attached to the horses' halters, worn by facility staff, and placed in strategic locations around the facility to monitor which participants had contact with the specified locations during the study period. When the tags came within 2m of each other, they recorded the contact event participant IDs, and start and end times. At the end of the study period, the data were downloaded to a computer and analyzed using network analysis methods. The resulting networks were plausible given the facility schedule as described in a survey completed by the facility manager. Furthermore, changes in the daily facility operations as described in the survey were reflected in the tag-collected data. In terms of the battery life, 88% of batteries maintained a charge for at least 6 days. Lastly, no consistent trends were evident in the horses' centrality metrics. This study demonstrates the utility of RFID tags for the collection of equine contact data. Future work should include the collection of contact data from multiple equine facilities to better characterize equine disease spread potential in Ontario.

The researchers have successfully used modified OpenBeacon RFID tags to map out equine contact networks over a week-long period. This technology offers a promising solution to tracking disease spread within equine populations.
Radio-Frequency Identification (RFID) Tags and Disease Spread
- Contact networks are used to predict disease spread among a population. In order to construct these networks, data about individual contact events must be collected. While this can be challenging, radio-frequency identification (RFID) tags offer one solution.
- The OpenBeacon RFID system typically consists of tags that communicate with readers when within 10 meters of them. However, in agricultural settings, these readers are difficult to implement due to the lack of a continuous power source and the large area to be covered.
Modifying OpenBeacon Firmware
- To overcome these challenges, the researchers modified the OpenBeacon firmware to store data in the tag’s onboard flash memory.
- These modified tags were then used in a case study at an equine facility. The tags were attached to horses’ halters, worn by staff members, and placed around the facility.
- Whenever two tags came within 2 meters of each other, the IDs and the start and end times of the contact event were recorded.
Results & Analysis
- The collected data was analyzed using network analysis methods. The resulting networks made sense given the facility schedule and daily operations reported by the facility manager.
- Any changes in the facility’s schedule were also reflected in the data recorded by the tags.
- Regarding battery life, most (88%) of the tag batteries lasted for at least 6 days.
- No clear patterns were found in the horses’ centrality metrics, suggesting no consistent contact trends among the horses.
Implications & Future Research
- This study shows that RFID tags can be useful tools for collecting data on equine interactions, providing insights into possible disease spread paths.
- In the future, researchers plan to gather contact data from multiple equine facilities to better understand the potential for disease spread among these populations in Ontario.
