Wilson said the co-op accepted the judgment.
"As the chairman and as a farmer I am angry and disappointed over the tribunal's decision in that it does not fully recognise the terms of the supply agreement that we had with Danone. However we do accept their judgment and we will turn our attention to delivering the best positive return to our farmers, despite this outcome, over the year ahead."
Asked if he thought the tribunal's decision would be the end of the matter, Wilson said: "From our perspective, it is entirely up to Danone in that respect, but it is our view that the claims that have been talked about by Danone have been effectively addressed in the arbitration, so it's up to Danone."
Danone's New Zealand subsidiary Danone Nutricia ended its supply contract with Fonterra in the wake of the botulism scare.
Since then, it has sourced product from Synlait Milk and other manufacturers and bought two Kiwi dairy processing companies, Sutton Group and Gardians, with the latter providing access to milk supply from 18 farms owned by Grant Paterson of Dunedin.
Chief executive Theo Spierings struck a conciliatory note in his comments about Danone — one of the world's largest food companies and, at the time, one of Fonterra's biggest customers.
"Before this unfortunate incident happened, Danone was a highly respected customer of ours, and still is in my mind," Spierings said.
"Danone is a global player and this is very unfortunate," he said. "We are open for commercial discussions [with Danone] and value creation rather than reliving and re-litigating the past."
Spierings said that, four years after the incident, Fonterra was in a strong position.
"It's very unlikely that there are options available to challenge this decision.
"Fonterra has learned from this experience — it was four years ago," he said.
"We have moved on. We are a much stronger co-operative now."
Spierings said Fonterra was looking at whether its insurance could cover all or part of the arbitration cost.
Rickey Ward, NZ equities manager at JBWere, said the market would be relieved that the claim was not higher.
"Despite provisioning for much less there had been growing speculation that a larger number would occur," Ward said.
Market speculation varied from a payment of $400m, with some analysts talking of a possible $1b payout.
"It provides certainty which will allow investors to finally focus on underlying fundamentals."
ASB rural economist Nathan Penny estimated the Danone award would take about 10c off Fonterra's total payout for 2017/18.
"While it's not going to break them [farmers] in any way, it is still a significant number," Penny said.
Fonterra is also due to update its milk price this month. Economists are expecting the forecast to drop to about 6.25/kg to $6.50/kg of milksolids from the current forecast of $6.75.
