Sour Steri Stumpie

I am honestly disappointed with Steri Stumpie, it is my families favourite milkshake drink and the best small gift I love to share but this is the second time I buy Steri Stumpie and it is sour. This makes me doubt the product. In 2015 my daughter left bottle milk and started drinking fresh milk I soon spoiler her with Steri Stumpie as I do with my family, but soon she got so sick and up to today 5 years later she does not eat or drink any milk products she believes that it taste like vomit this makes me wonder if those were also sour.

Highly disappointed and a waste of money of and over again. Hilda Farmer
