Pesto Deviled Eggs #ScienceSundays

The phrases “it’s what’s on the inside that counts” and “don’t just a book by its cover” also applies to eggs. It also helps when you add pesto to them ;-)

It’s the first Sunday of the month which means it’s time for another #ScienceSundays post. Last month I told you how eating raw flour can also increase the risk of foodborne illness, not just eggs. So I decided to continue on that stream of thought and talk more about eggs. As the second largest egg-producing state, Ohio is one of the few that voluntarily participates in an egg quality assurance program in an effort to minimize the risk of Salmonella in eggs. While pasteurized is the safest way to go, I admittedly don’t regularly buy them but also eat raw cookie dough with both raw eggs and raw flour so knowing my Ohio eggs are less risky is good to know. Despite my own warnings and a day job researching Salmonella I like to live on the edge when it comes to raw dough. But let’s turn our focus away from all the potentially gross gastrointestinal dilemmas.

Brown vs White Eggs

If you were presented with a white egg and a brown egg, which would you choose based on quality, flavor, and nutritional value? Trick question – the color of the egg has no relationship to any of these qualities. Why the different colors? It just depends on the breed of hen: white feathered hens lay while shelled eggs while red feathered hens lay brown-shelled eggs. It’s as simple as that. This also applies to how the hens are raised (organic, free-range, conventional) or grade (AA, A, or B). One way eggs can differ is if the hens are fed a diet enriched for nutrients (vitamin D, omega 3) which can enhance the already naturally nutritious egg.

To finish off today’s post I am sharing a recipe for pesto deviled eggs that ominously look like moldy rotten eggs. Bringing us full circle to not judging an egg by its shell. They are all deliciously nutritious, especially when you add pesto (and homemade to boot). To add to the potentially gross-factor, there were also skewered them with pipette tips (100% sterile) to bring to a “skewered masterpieces” potluck contest at work where you were judged based on creativity of the skewer itself in addition to the food. Yes I work in a microbial pathogenesis department which made the impact of the tips hit even closer to home.

I have friends who raised chickens and they had some pretty normal-looking chickens that laid blue eggs. Don’t remember the breed. I have decided that the best eggs to buy are from pasture-raised hens. I figure that if they live a more normal chicken life, the eggs will be less likely to harbor those nasty microorganisms. The ones I buy also have gorgeous orange yolks and taste better than your average commercial egg.

Oh yes, fresh will always taste best. I love those bright orange yolks too. As for the microorganisms, I don’t think there has been any correlation to how they are raised and the chances of contamination.
