It’s been a busy week in food news at WBUR.

Trick, or Treat?
First, “Radio Boston” picked up the thread of a major investigation published Monday by the Boston Globe, which reported on the willful and frequent mislabeling of fish by big names in the Massachusetts seafood processing industry.This means there’s a good chance that the tuna you think you are eating isn’t actually tuna. It could be escolar, or “snake mackerel,” a different fish species entirely and one that sells for 20% less than white tuna. Guess the chances of that price differential being passed on to you. Concerned? Listen to Radio Boston’s take on this controversial news story.

The Communal Table
On Tuesday, New Yorker writer Adam Gopnik joined “On Point” to talk about the meaning of food and the ‘why’ and ‘how’ we share it. His conversation with Tom Ashbrook takes as its jumping-off point a letter penned in 1942 by a French Resistance fighter three hours before his execution. “Questions of food have taken on great importance.” Indeed. The doomed man’s letter invigorates Gopnik’s thinking in his new book The Table Comes First: Family, France and the Meaning of Food.

Brown is the new Green
On Thursday, “Here & Now” aired a segment about the so-called “Brown Revolution.”  This form of ‘holistic land management,’ begun in Africa some 40 years ago, uses large grazing animals (e.g., cows) to restore dried-out grasslands, improve water tables and mitigate global warming. Sacha Pfeiffer speaks with Colorado rancher Jim Howell, co-founder/CEO of Grasslands LLC, and Brandon Dalton, a rancher and wildlife biologist, about the details. It’s a logical, fascinating concept; cows and goats get to do the ‘wild’ thing with the all-important action of their hooves.

A Shangri-la of flavor
“Radio Boston” finishes off the week with a visit to a Dartmouth farm named “Eva’s Garden,” three acres with more than 200 uncommon herbs, greens and edible weeds. Chef Didi Emmons calls it a Shangri-la of flavor, whose high-priestess is Eva Sommaripa, a woman who’s a veritable encyclopedia of botanical knowledge. “Radio Boston” co-host Meghna Chakrabarti paid a visit; listen in.
