growing demand. the company and the f.d.a. claim it is safe to eat. critics say the fish could cause unknown allergic reaction and potentially damage the wild salmon population. and now, we have assistant director of the consumer group food and water watch. good to see you. guest: thank you. shepard: when you talk about altering, people say tell me more. some fear it could get into the wild salmon population. guest: we hear how it will be contained by the company but the plan for the salmon is to grow them in panama and send the fish here for us to eat and the f.d.a. is doing a terrible job on food imports and they to not have a way to check if they are raised in a containd way. so we need to look at all the possible impacts if this could hurt wild populations if there is an accident.
