The International Dairy Foods Association lists several protocols (time and temperature) for pasteurization, including ultra-pasteurized, which can be stored at room temperature. The US uses mostly 15 s, 72 °C. I wonder if the difference is merely which protocol is preferred or required. I can't imagine we would quibble over whether the temperature is stated in °C or °F as long as they were equivalent. http://www.idfa.org/news-views/media-kits/milk/pasteurization From: Michael Payne <metricmik...@gmail.com> To: U.S. Metric Association <usma@colostate.edu> Sent: Thursday, April 2, 2015 8:20 AM Subject: [USMA:54674] Troubling agreement I just happened to be listening to the CBC news early this morning was half asleep but paid more attention when I realized they were discussing an apparent agreement for Canada to drop some of it’s metric requirements for trade with the USA (NAFTA?), they talked about pasteurization temperatures as an example, from the sound of the conversation this was being pushed on Canada by the Washington based trade negotiator, the presenter seemed a little aghast that this could happen,
I’ve not had time to google this apart from a cursory “Canada to drop metric system nafta” query which didn’t seem to bring up anything. Later on I’ll be able to spend a bit more time researching this, but I’m really amazed that this is being stuffed down the throats of the Canadians. Mike Payne
