A way to solve pig waste issue

I REFER to the news report, “Seafood ‘gone to the pigs’” (Sept 15, The Star) in which it was reported that marine biologists warn that because the beach of Gertak Sanggul is a sheltered bay, extreme bacterial blooms can infect Gertak Sanggul’s seafood with harmful pathogens from salmonella bacteria to E coli and even Hepatitis A virus.

When I was in the Veterinary Services Department, we found a high level of copper in pig waste, which can cause copper toxicity. The high level of copper is due to the copper content in the anthelmintics (worm treatment) the pigs are regularly dosed with.
