“Something fishy going on”: Mzansi reacts to herpes virus found in SA sardines

South Africans are on high alert after the Department of Forestry, Fisheries and the Environment (DFFE) confirmed a rare virus discovery. For the first time ever in local waters, pilchard herpesvirus (PHV) has been identified in sardines.

The investigation began in early August 2026 after thousands of dead fish were spotted along the West Coast. The mortality event stretched significantly, covering the coastline between Saldanha Bay and Gansbaai.

Laboratory Findings and Safety Concerns

Testing conducted in specialized laboratories confirmed the presence of PHV in the deceased sardines. While some healthy-looking fish also carried the virus, it was found at much lower concentrations than in those that perished.

Scientists also looked for toxins from algal blooms, such as yessotoxin and domoic acid. While these substances were detected, the DFFE noted the levels were too low to be considered the primary driver of the mass deaths.

Addressing public fear, the department emphasized that the discovery "does not indicate that healthy sardines caught commercially or canned products are unsafe." There is currently no evidence suggesting the virus can jump to humans or other animal species.

A Coordinated National Response

Because this is a new phenomenon for the region, the government is not taking any chances. A task team featuring industry stakeholders and environmental experts is being formed to handle the crisis.

This team will work to "urgently formulate a high-level coordinated response plan for PHV-associated sardine mortality in South African waters." For now, commercial fishing and canning operations will continue without suspension.

Mzansi Weighs In

Social media users were quick to react to the news, with many expressing disgust or cracking jokes about the situation. The news went viral on X, leaving many consumers questioning their dinner choices despite the safety assurances.

While the authorities maintain that the food supply is secure, the sight of mass die-offs has left a lingering sense of unease. Residents along the West Coast continue to monitor the shoreline as the investigation into the virus's origin continues.
