Modern-day slaves are working in our food supply — but it's a problem that can be fixed

  • Governments and the seafood industry would dramatically improve their ability to identify and suppress human trafficking if they focused on the subtler "invisible" abuses of power.

  • The operators of complex supply chains should seek feedback from workers rather than relying on traditional audits and inspections.

Non-profits and news organizations have uncovered egregious human rights abuses in the seafood industry that urgently need to be addressed by both government and business.

But the problem has to be attacked in the right way if it's going to be stopped, and that means understanding how to find it.

There's a large body of evidence that Southeast Asia migration among workers in low-skilled industries such as seafood fishing is positive overall — not only for millions of migrants and their families, but also for businesses producing U.S.- and Europe-bound products. For concerned retailers and consumers who want to avoid food tainted by slavery, the question is, "merchants that treat their workers well?"

There can be thousands of migrant workers aboard fishing vessels, in small production plants, on farms, and within factories associated with the production of just a single bag of shrimp. So the first problem we have to solve is finding the human trafficking within these very complex supply chains.

Issara Institute conducted a groundbreaking study to zero in on that problem for the fishing industry, and the findings provided an enlightening but sobering view of what labor trafficking in supply chains looks like.

Of the hundreds of fishermen we interviewed across Thailand , overwork with illegally excessive hours, illegally low pay, and debt bondage — key elements of human trafficking — were widespread, impacting more than 75 percent of respondents at some point over the past five years. However, rates of physical abuse and violence — one of the primary indicators of human trafficking in the eyes of government — was found to be significantly less prevalent, directly affecting only 18 percent of fishermen interviewed.

With all the media reports about violence, murder and slavery at sea, those findings may come as a surprise to some people. However, they make sense from an economic perspective: Labor shortages are severe in countries like Thailand and Malaysia , where most of the local population does not to want to do "3D" (dirty, dangerous, demanding) jobs. Stable production of export commodities depends on a highly productive migrant workforce, often kept in place through legal, physical or financial coercion — but not as often by physical abuse, because that would hurt health and productivity.
