On Tuesday last week, the Royal Society for the Prevention of Cruelty to Animals (RSPCA) issued a press release about the “incredible story” of Marina, a seal it rescued, that had become trapped under a rock on a beach in South Wales. “Moving a three-tonne boulder presents numerous challenges, but we were able to work with partners to free this seal, before giving her the six months of rehabilitation she so urgently needed.” Marina’s rescue is “testimony to the RSPCA’s tireless commitment to wild animals and their welfare.”On the same day, the RSPCA’s head of campaigns, pushed into a corner during an online argument, wrote this: “Seal shooting is not culling it’s about humane pest control.” He was defending the slaughter of seals by Scottish salmon farms.The contradiction is at first sight incomprehensible. But alongside its spectacular rescues of animals like Marina, the organization has another role, which is to assess livestock farms, and award those that meet its standards its RSPCA Assured label. This seal of approval ensures that “you can feel good about your choice when shopping and eating out”. Of the 280 million animals whose production and slaughter it approves every year, salmon account for 200 million. The RSPCA accredits 63% of Scottish salmon farms.
