Imagine the scene – Tom and Mary are both working in white-collar jobs as did their parents before them. They have four small children. They are dedicated parents and they would like their children to experience a bit of country life. Where better then to head for than the local open farm. The first thing to be done is to buy the kids nice wellies, then pack a really nice picnic. There’s great excitement at seeing the baby animals. Mammy and Daddy caution about rubbing the animals and getting too close. All goes well until picnic time. The rug is laid down and the food is put out. But does anyone think of washing the little hands after contact with animals?
