No food safety risk associated with fish oil supplements
The Ministry for Primary Industries (MPI) and the Ministry of Health are confident a recent study provides no evidence
of a food safety risk associated with fish oil supplements currently on the New Zealand market.
Jenny Reid, MPI Manager Food Science and Risk Assessment says the recently published Liggins Institute study that gave
highly oxidised fish oil supplements to pregnant rats does not identify a risk to pregnant women.
“The fish oil that was given to the pregnant rats in the Liggins Institute’s study was artificially oxidised to an
extremely high level, far higher than that found in fish oil supplements currently on the market. It is extremely
unlikely that oxidisation of any product on the New Zealand market containing unsaturated fats would reach these
levels,” says Ms Reid.
In April 2015 MPI commissioned a review of the published data on the toxicity of oxidised fish oils
. The review did not identify any concern.
“The quantity given to the pregnant rats was greater than the recommended dose and therefore more than a human could, or
should, consume within a day.
“The study does not identify whether oxidation of fish oil is a health risk in human pregnancy,” says Ms Reid.
The Ministry of Health Acting Director of Public Health, Dr Stewart Jessamine, says its advice to pregnant women is, and
always has been, to eat a healthy, well-balanced diet and where practical to get your essential nutrients from foods,
“There is nothing in the study to suggest there is a risk to pregnant women. Consumers may choose to take dietary
supplements, but the best source of omega 3 is from fresh fish. If people do not like fish then I encourage them to talk
to a registered dietitian regarding other sources of omega 3,” says Dr Jessamine.
