AquaBounty says its first bioengineered salmon will be harvested in March, but that doesn’t mean it’ll be easy to buy.

For decades, Americans have been teased with the impending arrival of genetically engineered salmon. If a boycott campaign continues apace, they may have to wait even longer.

Earlier this month, a coalition of environmentalists and grassroots organizers announced they had successfully pressured Aramark, one of the country’s largest foodservice companies, into agreeing not to sell the salmon, should it become available in the United States.
