OUT AND ABOUT Door closer


I am sure it is a cry you are familiar with: a kind – or not so kind – request to your pickers to please keep the door to the growing room closed. Growers and farm managers often know better than their employees do just how quickly infections can start.


I often hear growers exclaim: “Hey, shut the door!’’ It is a good idea to explain to your staff why it is so important to keep the doors closed, certainly if there are flies on the farm as well as any infections affecting your mushrooms. All kinds of methods are used to help control pest and diseases, but in our modern food safety conscious times there are hardly any chemical agents that can be deployed, or none at all. Prevention works better than cure, and that implies observing strict hygiene protocols on today’s modern farms. While I was ‘out and about’ at one of my client’s farms in the USA, I came across a really simple practical solution that can easily and effectively solve the problem of open doors. A door closer like the one shown in the photo seemed to be the ultimate solution. The farm I am talking about is a large, modern facility, built in the Dutch style, where six doubled-door growing rooms are filled each week. In practice, that means that a growing room is filled six days each week. It goes without saying that keeping the doors closed is vital, especially at filling. The farm is question is entirely free of flies and scariads, which is also thanks to their scrupulous hygiene policy. And that includes keeping the doors closed as much as possible. Spores of cobweb mould and dry bubble are spread before you realise, particularly as the over pressure in the growing rooms can easily blow mould spores into the cor- ridor. An open door from the growing room being filled to the corridor has virtually none, or only very limited, over pressure during filling, so you can imagine what could happen to any mould spores in the corridor.
