That mild, affordable tilapia fillet on your plate has a complex backstory. While marketed as a healthy protein source, the truth about tilapia farming might make you think twice before your next purchase. This freshwater fish, originally from Africa, has become an industrial farming phenomenon – with both nutritional benefits and environmental concerns.

The good news first: Tilapia provides lean protein and important vitamins at a lower cost than many other fish. However, mass production has led to troubling practices at some farms, particularly in Asia. Picture overcrowded ponds where fish are fed unconventional (and unsanitary) food sources, potentially passing contaminants to consumers.
Eco-conscious eaters should seek out tilapia from certified sustainable sources. Look for fish raised in recirculating systems (common in U.S. farms) or from South American producers known for better standards. Your best bet? Check for reliable certifications that ensure both food safety and environmental responsibility.
