A new report sheds light on the abused immigrants shucking your shellfish.

It’s been an ugly year for the seafood industry. Investigative reports by both the AP and the New York Times exposed widespread reliance on forced and slave labor from international seafood suppliers across Southeast Asia, prompting President Obama to sign the Trade Facilitation and Trade Enforcement Act in February. The bill banned the import of goods produced with forced labor, a concerted conclusion to months of startling headlines.

But labor abuse in the seafood sector isn’t a problem confined to Asia. A report published Wednesday by the labor group the National Guestworker Alliance suggests that some US seafood workers also experience abusive conditions. The report focuses on the experiences of undocumented and H2-B visa guestworkers shucking, peeling, and boiling shrimp and crawfish at seafood processing plants in New Bedford, Mass. and along the Louisiana Gulf Coast. Around 69 percent of shrimp produced in the US comes from the Gulf Coast.

According to the NGA report, the US seafood industry has relied heavily on H2-B guestworkers and undocumented immigrants to drive down labor costs to stay price competitive with international producers. A 2009 survey in New Bedford found that nearly 75 percent of the workers in its seafood processing industry were undocumented immigrants. The US Department of Labor certified over 5,700 H2-B visas for seafood related positions in 2014, a marked 15 percent increase over 2013. Because employers grant H2-B visas, those on the receiving end are particularly vulnerable. Due to threats of retaliation by employers—including firing, which can result in deportation—guestworkers are often hesitant to report mistreatment. “Hours were long, wages were bad, housing was terrible—but we were all afraid that if we spoke up, we would lose our jobs, our housing, and our ability to ever come back to the US to work,” longtime H-2B guestworker Olivia Guzman Garfias told the NGA.

Here are some more striking details from the NGA’s report:

  • In housing provided by processing companies in both the Louisiana Gulf and New Bedford, Mass., workers reported living with up to 20 people per trailer, without access to proper sanitation and sometimes with strict curfews.
  • Of the 126 seafood workers surveyed in New Bedford, 25 percent reported having been injured on the job. The majority of workers reported having to purchase their own safety equipment.
  • 44 percent reported not being paid for overtime work.
  • At times, piece rates for pounds of shrimp prorated to levels well below minimum wage, as low as $2 per hour, and employers sometimes failed to pay promised rates. According to NGA Organizing Director Jacob Horwitz: “Stealing wages is standard business practice. The financial incentive to underpay guestworkers is far greater than the risk of getting caught.”
  • Female workers experienced sexual harassment and verbal abuse in the workplace as well as in company-provided housing. Some women spoke of unwanted sexual advances by company brass, and of being fired for rebuffing such advances.
