It’s All A Matter Of Taste Or Is It?

Thursday, August 27th, 2009

I just saw a movie which took me through the first chapters of Julia Child’s life-long venture with French cooking. Having been a French major in college, I must confess, that Julia’s first cookbook, Mastering the Art of French Cooking, became basic reading just like Le Petit Prince (The Little Prince by Antoine de Saint Exupéry), which brings me to today’s blog. While Julia Child is to be credited with opening Americans’ eyes to new French culinary techniques, we must note that her advice was ahead of its time. Not only did Ms. Child adapt ingredients to those which would be easily found in the traditional American kitchen and supermarkets, she is also credited with educating chefs-in-training on the importance of using fresh seasonal ingredients whenever possible. In her cookbooks, she even highlights during which months taste is optimum for specific produce. Essentially, in the early sixties, Julia Child was already a locavore way before the term had been coined. I don’t think reducing her carbon footprint was what she had in mind. For her, it was a matter of taste.

That brings me to the other issue I would like to discuss today–eating fresh fish. While eating fish and seafood is an essential part of a healthy diet, whether you’re a famous chef or not, many people argue that fresh fish actually tastes better. Well, freshly caught fish is more difficult to find nowadays. As I was reading several articles on aquaculture, I was surprised to learn that nearly half of all fish eaten today are actually farmed, not caught in the open seas or fresh waters. Back in 1980, the percentage of farmed-raised fish that made it to our tables was only 9 percent! Aquaculturists are even developing techniques so the farmed-raised fish will actually taste “fresh.” Given the growing population, good aquaculture practices are key to ensuring a sustainable supply of fish for human consumption. According to a recent study, there seems to be some hope for fisheries worldwide.

I would like to get input as to your thoughts on the issue. Personally, it all boils down to the taste of food—or does it really? In conclusion, bon appétit! As Julia Child used to say….

Collaboration is Key to Environmental Monitoring

Tuesday, August 18th, 2009

March 2009 marked a memorable month in the 19 years I have worked for EPA’s Office of Water. That is when Environmental Monitoring and Assessment published two articles about EPA’s National Lake Fish Tissue Study. I had the privilege of managing this study for the 8 years required to complete it.

It also included the largest set of chemicals (268) ever studied in fish. Field crews worked 4 years to collect fish samples from 500 lakes selected randomly from a statistically-defined set of about 147,000 lakes in the lower 48 states. Tony Olsen in EPA’s Office of Research and Development designed the study and directed statistical analysis of the concentration data. The design of this study generated results that allowed EPA to estimate the percentage of lakes and reservoirs across the country with fish tissue concentrations of specific chemicals, such as mercury, above levels of concern for human health.

Aside from my intense feeling of pride in providing leadership for this major scientific study, I look back in amazement at the number of people who volunteered years of effort to make this study possible. EPA relied on the participation of scientists from 58 state, tribal, and federal agencies for 5 years to evaluate sampling sites and collect fish samples. Their long-term commitment to maintaining the highest standards of quality while participating in the study produced scientific results that earned the praise of senior EPA managers, industry representatives, and members of academia. I want to extend my heartfelt appreciation to all of the scientists across the country that support EPA. In the end, it was their hard work and dedication that made this study a success.

Flying Fish

About the author: Jeffery Robichaud is a second generation scientist with EPA who started in 1998. He serves as Chief of the Environmental Assessment and Monitoring Branch in Kansas City.

Ever heard of a guy named Lew Zealand? He was the Muppet that threw boomerang fish (I expect a cut of your winnings if you ever go on Jeopardy and this bit of trivia pays off). I thought of Lew because it is field season again and on the Missouri River we have our own airborne fish. They are Asian Carp, a particularly troubling invasive species that have infested waters and pose a potentially devastating effect to the Great Lakes. They were introduced into the catfish aquaculture business in the 1970s but during floods these “prisoners” escaped their ponds into the Mississippi River, and have been on the run ever since. YouTube has a lot of great videos of them in action.

In Region 7 we administer our Regional Ambient Fish Tissue (RAFT) program where samples are analyzed for contaminants such as mercury, pesticides, and PCBs. States use the data to post fish advisories. Our biologists (including Lorenzo pictured here) end up with nets full of carp because they often are the most abundant fish in the Missouri River. If you talk to some of the old timers fishing along the banks they will tell you the odd-looking paddlefish were more abundant in years past. Paddlefish face many challenges from human-induced changes to the river such as dams, loss of habitat due to channel straightening, and illegal harvest of eggs for use as caviar. Now they count flying fish as enemies since the more abundant carp out-compete the paddlefish for food.

A plant may look pretty and an animal may seem cute, yet they may wreak devastating damage when introduced into a non-native setting. In 1884 a single Australian released twenty-four European rabbits on his property for hunting purposes. Within ten years those 24 had turned into over 2 million, and started the delicate ecology of Australia into a downward spiral causing hundreds of millions of dollars of damage each year and bringing a $30,000 fine for anyone found harboring their own long-eared friend as a pet.
