  • Raw tuna contains harmful bacteria e.g. Campylobactuer etc. which on ingestion can lead to deadly infections.
  • Tuna usually feed on small fish in the ocean which may contain mercury. They also absorb mercury through their skin present in ocean water from contamination with fossil fuels(3). If fed in high amounts poisoning usually results. This also applies to sodium which is also present in tuna.
  • Canned tuna packed with oils can cause pancreatitis, obesity, heart and liver disease if feed in excess. Those packed in water are a healthier option.

Conclusions

Tuna is a healthy source of protein, essential oils and minerals which help in the growth and repair of body tissues.

Raw tuna contains harmful bacteria which cause deadly infections if not treated. Cooked or canned tuna is therefore preferred.

Mercury and sodium are also commonly found in tuna. Excessive feeding can lead to poisoning and death. Water canned tuna is a healthier option to oil packed tuna as the oils can cause pancreatitis and obesity.

Though tuna has dietary benefits for dogs, caution should be observed during feeding by monitoring the amount fed to avoid its harmful effects.
