Food science cafe

We had our first, monthly, Food Science Café, last night, and while numbers were small, I still believe that, if you build it, they will come.

As long as it’s useful.

Adrianna Deweese of the Kansas State Collegian wrote that Douglas Powell, scientific director of the International Food Safety Network at K-State, said the purpose of the monthly discussions is to talk about food safety and science in a different setting than a classroom.

Powell showed his meat thermometer to those in attendance, and said it is important to get a digital, instant-read, tip-sensitive meat thermometer, which costs about $12.

"Lots of people use it for whole birds or roasts, but I think it’s more important actually for the burgers and the ground beef," Powell said. "Ten years ago I would have never used one, but now I feel naked when I don’t – I feel vulnerable."

When he is asked at a restaurant how he would like his hamburger cooked, Powell said he responds he would like it "160," meaning he would like it cooked to 160 degrees Fahrenheit.

Food color often is a poor indicator of when it is properly cooked, Powell said. K-State food-safety research has found about 25 percent of tested hamburgers turned brown before they reached a safe temperature of 160 degrees Fahrenheit, he said.

"We’re always just trying to find one way to put information out and take information in," he said. "We’re just always trying to find new ways to get it out there so we have fewer sick people."

The network also has several blogs at www.donteatpoop.k-state.edu and
barfblog.foodsafety.ksu.edu. Powell also wore a T-shirt Monday night that said "ne mangez pas de caca," which is French for "Don’t eat poop."

"It’s had more effect than anything else," Powell said of the message.

Angela Dodd, senior in food science, was quoted as saying Food Science Café discussions are

"a great way for students to become aware of what’s going on in the media about food safety. Food pertains to everybody, and it’s a part of everybody’s life."

I didn’t really like the long table set-up. Next month, we’re probably going to do it in the on-campus bowling alley. Only place to get a beer at K-State.

Power from poultry poop, and a science oops

Two stories in Animalnet today struck me as kind of fun.

The first one, about using turkey manure appeared on Minnesota’s TV KARE 11 website.  Minnesota Governer Tim Pawletny was quoted as saying "There is gold in that there manure."  The story suggests that 100 semi-truck loads of turkey manure provides the fuel to power 40,000 homes.
The $200 million 54 megawatt plant is owned by Fibrominn, a subsidiary of a British company that operates three similar plants in Great Britain.

The story says that for Minnesota turkey farmers it’s a dream come true; free trucking and a small payment for manure.  What interests me is how this power-from-poop impacts biosecurity practices and controlling animal diseases.  I wonder if and how the trucks are cleaned between loads, and what would happen if avian influenza (high or low pathogenic) appeared in Minnesota. 

The second story that I loved today appeared in Saturday’s New York Times and was about state and federal biologists in Colorado recently learning that they may have been protecting the wrong species of fish for the past 20 years.

It seems that the biologists have been trying to restore the rare greenback cutthroat trout to Colorado waters, but were actually saving the similar but more common Colorado River cutthroat trout.
A three-year study led by University of Colorado researchers and published in August found that out of nine fish populations believed to be descendants of original greenbacks, five were actually Colorado River cutthroat trout.

Tom Nesler, state biologist was quoted as saying (maybe the best quote I’ve seen in the past month or so) “Hey, science happens.”   New developments in DNA testing have illuminated the problem,  Nesler was quoted as saying that  "Up until a year ago, no one could tell us the difference between the two."
