Bonsoy Milk Class Action

The Bonsoy Milk class action will be conducted by Maurice Blackburn in the Supreme Court of Victoria seeking compensation for people from around Australia who have suffered an injury from consuming Bonsoy milk.

The proposed claim

Bonsoy soy milk is distributed throughout Australia by Spiral Foods Pty Ltd. Prior to December 2009, Bonsoy was sold widely in most supermarkets as well as health food shops and cafes.

At that time Bonsoy was enriched with a kombu extract which is a type of seaweed and very rich in iodine. Iodine is necessary for thyroid function, but is only required in very small amounts. Excess amounts of iodine can affect the thyroid and cause illness which may be severe.

The Bonsoy milk recall

In late December 2009, Spiral Products Pty Ltd voluntarily withdrew Bonsoy from the Australian market when it was discovered that it contained extremely high levels of iodine which could lead to serious health problems.  The level of iodine in one glass of Bonsoy was found to be around 7 times the safe upper limit for adults. Drinking 30mg of Bonsoy a day for adults, or 5mg for a child, resulted in consumption of unsafe levels of iodine.

The recall occurred after people suffered serious health problems caused by Bonsoy consumption including hyperthyroidism and hypothyroidism. These conditions of the thyroid can result in the following symptoms:

  • extreme fatigue
  • shortness of breath
  • heart palpitations and in severe cases heart attacks
  • sudden and severe weight loss or weight gain
  • loss of muscle tone and function
  • pain in the muscles
  • swelling of limbs
  • anxiety
  • depression and mental disturbance
  • hair loss
  • menstrual irregularities in women
  • miscarriage
  • intolerance to cold or heat
  • skin rashes and peeling
  • eye conditions including permanent eyesight damage
  • obviously enlarged thyroid gland

These symptoms may have a gradual or sudden onset and continue for months or years while excess iodine is consumed.

Who is affected by the class action?

If successful, the Bonsoy class action will benefit people who suffered thyroid conditions and injury due to the consumption of Bonsoy milk from at least 2003 up to the end of 2009.
