Summary

In 2022, workers at the Southern Africa Ferro Alloys Limited (SAFAL) plant at Kanona, Serenje, developed tremors, loss of balance and speech difficulties. The government told Parliament in March 2023 that 271 of 281 employees tested had blood manganese above normal, that 28 had symptoms, and that the exposure followed the use of a fine manganese concentrate from San He Mining Limited between March and September 2022 (Hansard).

ZEMA seized the concentrate in March 2023 (Zambia Monitor). Workers’ Compensation Fund payments began in April 2024, and in 2025 SAFAL began building houses for affected former workers (MakanDay). Former workers and civil society say the compensation and medical support are inadequate (Zambia Monitor).

AMAP has asked SAFAL and the responsible authorities to respond.

What happened

Workers at the SAFAL plant developed tremors, loss of balance and speech difficulties. The government attributes the exposure to dust from a fine manganese concentrate used between March and September 2022, and found blood manganese above normal in 271 of 281 workers tested.

Civil society has suggested a chemical additive was also involved; this has not been confirmed by any official finding. Former workers also allege that protective equipment was inadequate; the company has disputed that the illness was caused at work.

Impact on workers

  • Health: a lasting, Parkinson’s-like condition in the most affected workers.
  • Daily life: some cannot walk unaided or speak clearly, and take many medicines a day.
  • Income: monthly compensation payments far below former salaries.
  • Compensation: company-built houses; workers report not holding copies of the agreements they signed.

Rights at stake

The rights at stake include the right to safe and healthy working conditions, the right to health, the right to information and informed consent in settlements, and the right of those harmed to an effective remedy.

AMAP does not determine whether the law was broken, who is legally responsible, or what compensation is owed; those are matters for regulators and courts. AMAP documents what has been reported, presents the evidence, and asks those with responsibility to respond.

What happens next

SAFAL and the authorities AMAP has contacted have been asked to respond by 16 October 2026. Responses will be published on this page in full.

Names of the former workers shown are withheld, and no medical records are published on this page.

  • August 2025

Assessment so far

  • EstablishedThe government found blood manganese above normal in 271 of 281 SAFAL workers tested, linked the exposure to a concentrate used in 2022, and reported 28 workers with symptoms. ZEMA seized the concentrate in 2023. Compensation payments and company-built houses followed.
  • Disputed or unresolvedThe number now severely affected (28 by the government’s count, 35 by CEJ’s); whether anything other than manganese dust was involved; the adequacy of protective equipment before 2022; the terms of the compensation agreements and how they were signed; and the findings of the joint inspection.
  • Outside AMAP’s roleMaking medical findings, determining legal responsibility, or deciding the compensation owed.

What would help clarify: the joint inspection report, follow-up medical surveillance results, copies of the compensation agreements, and the Workers’ Compensation Fund’s assessments.
