Rohana Subasinghe, senior fishery resources officer for aquaculture at the United Nations’ Food and Agriculture Organization, says: “In my opinion and experience, the use of banned antibiotics and fungicides in Asia has decreased considerably....  I do not deny that farmers use banned antibiotics and fungicides.  But the usage has reduced significantly.”
 
Small farmers produce about 80 percent of the world’s farmed seafood, and most of those who use illegal veterinary drugs are unaware that they’re using them, notes Subasinghe.  “These people are not necessarily very well educated,” he says.  “So it is our responsibility to empower them to do a better job.  It’s extremely important to make them aware of global food safety requirements and international trading standards—what’s supposed to be used and what’s not supposed to be used.  Extension is a must.  However, many governments are becoming increasingly incapable of providing good extension.”
 
“In many countries, you can buy fish feed containing illegal veterinary drugs on the open market,” adds Subasinghe.  “When it’s freely available, you’re basically setting a precedence for increased usage.”
 
Bill More, director and VP of the Aquaculture Certification Council in Kirkland, Washington, USA, puts some of the responsibility on feed manufacturers because antibiotics are administered mostly through feed.  “Unscrupulous salesmen sell farmers feed containing illegal veterinary drugs and don’t tell them what it really is”, says More.  “You’ll see products like ‘Make Your Shrimp Grow Faster’ and ‘Happy Shrimp,’ but they don’t tell you what’s in the product; the government doesn’t always require it.  Small farmers, especially, have been taken advantage of.”
 
More also believes that the use of illegal veterinary drugs in Asia is falling.  “It’s very rare now that we find a product that tests positive,” says More.  “This year, we’ve taken over 1,000 tests from China alone from the two plants that we certified.  We’re making them submit tests through third-party labs every week.  These two facilities have been completely clean for almost two years now.  But these...plants...sell to companies like Darden and Wal-Mart,” he adds.  “So you really don’t expect to find tainted product in plants like that.  It’s the other plants you have to worry about.  Most conscientious farms, especially those integrated with processing plants, don’t use illegal antibiotics and fungicides anymore.”
 
George Chamberlain, president of the Global Aquaculture Alliance in St. Louis, Missouri, USA, says: “Fishmeal prices have been quite high.  So every feed manufacturer in the world is looking for ways to minimize the fishmeal inclusion level by utilizing alternate sources of proteins and fats.  In China, what would normally be typical alternatives, for example, rendered animal products, are huge red flags because they can’t be sure that they are absolutely free of all illegal antibiotics.”
 
“The whole point is to test upstream and reduce the need to test at the end of the pipeline,” explains Chamberlain.  “With end-of-the-pipeline testing, where millions of pounds of product are emptying into ports of entry, attempting to understand the history of a product with a few spot tests is futile.  It’s much more productive to test at the point of origin.”
 
The ACC recently added fluoroquinolones—including ciprofloxacin, enrofloxacin, sarafloxacin, flumequine and oxolinic acid—to the list of antibiotics that private labs are required to test for when it certifies shrimp farms.
