Food manufacturer Tiger Brands has announced the recall of 20 million canned KOO and Hugo vegetable brands due to a leak.

The company made the announcement on Monday morning, saying the leak is caused by a defective side seam weld.

Tiger Brands says the financial impact of the recall is estimated at between R500 million and R650 million.

The company says most of the defective cans were identified prior to the final labelling of the finished products.

But it has decided to recall all the affected canned brands manufactured between 1 May 2019 and 5 May 2021. These include KOO and Hugo Baked Beans and mixed vegetables.

Tiger Brand says the leak can present a risk of secondary microbial contamination with low probability of illness and injury when consumed.
