Thank you for submitting the report. Nutria can become habituated to being fed and often reside in locations where human traffic is common. It is important for people to realize that nutria are rodents and potential reservoirs for a variety of diseases. The nutria page on the Center for Lakes and Reservoirs website at contains information on nutria diseases. My contact information can also be found on this site if you have questions or would like further information.
