Hair Found in Similac Formula

For an entire year, I faithfully relied on Similac formula. However, much to my dismay, I recently made a rather unsettling discovery - a strand of hair nestled within the box! How is it possible for baby formula to contain human hair? This is not acceptable. It is important to ensure that these products remain untouched and sterile. It is important to adhere to proper hygiene protocols. I have an unopened box that I'm a bit unsure about using. Such a frivolous expenditure!
