Why do you think someone is poisoning food at the Supermarket? What is their motive?

Absolutely no idea!

Are they trying to get the supermarket to stop building on that field, or have it in for the company. Other than that not really got any theories at this stage.

To take revenge on the company for some reason known only to them

Revenge, notoriety...to watch the chaos... get their deed in the news...who can say?

Yes I think they want to stop the building of a new supermarket for some reason.

My thought was that they wanted to stop the excavation of the field.
