Dunkerton Co-op prides itself on being a single entity location.  Servicing our customers that depend on us is contigent on the wellbeing, health and safety of our employees and is of the highest priority.  Because of this, we ask everyone that we do business with to abide by the following:

*If you have traveled outside of the state, please consider doing buisness by phone or email. 
*If you have been sick, are not feeling well or have been around individuals that have been sick, please refrain from coming into the office.  If you need something, please call us and we can make arrangments over the phone. 

*If you do come into the office, please use the south glass door and come to the counter and then leave via the same door.

*Please respect our employees with social distancing.  Maintain a 3 to 6 food distance and avoid hand-shake greetings.

We are continuing to do business as normal with feed deliveries, receiving grain and ingredients and receving and loading out fertilzier.
