Shatto owner, Leroy Shatto showed off the bells and whistles on the company milk truck to the group from Ireland.
He's still in awe of the big names in the bunch.
"We had the Minister of Agriculture and all these big people here from Ireland. What's up with that? It's crazy for those people to want to come to Clinton County and want to come to our dairy. It's unbelievable," said Shatto.
Hayes dropped by Shatto after touring other farms in the area, and said he's impressed with the Midwest.
"I enjoyed visiting the different farms, and seeing how efficient they are, how business-like they are, and how committed to the land and to producing good food they are. I'm very taken with that," said Hayes.
Even though he's a long way from home, the minister had no trouble finding similarities.
"They're custodians of the land, these people. They're the people that I think are so valuable. They're entrusted with the land, as they are in Ireland and they'll pass it on to the next generation," said Hayes.
Hayes was in Missouri to get a look at the rich agriculture, and find opportunities or ideas to bring back home with him.
It's also a chance to discuss the struggles that sometimes go hand in hand with rural life.
"We're going forward in a very challenging world. The population is growing and we need more food. We need more good food to feed the people," said Hayes.
"Being a dairy farmer in the United States, we always thought we were the ones that didn't make as much money as everybody else, but they're having problems too," said Shatto.
After Irish leaders toured the dairy farm last year, Leroy Shatto took a trip to Ireland and says he's already planning his next trip there.
