When they say contaminate they are talking about things such as soil or dirt or unsanitized areas that could contain microbes that could damage the ecosystem.
To use a metaphor, when sailors visited the islands the Dodos were on, there were rats on their ships, which eventually wiped out the Dodos (among other factors). The rats are essentially the contaminant, where as the ship is the probe.
They have to be very careful to not introduce anything potentially harmful in to this sealed ecosystem, that they can not observe without risk.
