A Pennsylvania-based company is recalling several of its protein drinks because they may be contaminated with Clostridium botulinum, a bacteria that can cause a life-threatening illness in humans when ingested.

Protica, Inc. of Whitehall, PA issued a voluntary recall of its Body Choice “Protein Shots,” Nutritional Resources “Protein Wave,” ProBalance “Protein to Go French Vanilla Latte” and “Protein to Go Milk Shake” Thursday after an on-site investigation revealed that they were being processed in a way that is not guaranteed to prevent the growth of Clostridium botulinum.

Toxins produced by this bacteria attack the nervous system and can cause paralysis and even death.

Products subject to the recall include:

– Protein to Go Milk Chocolate Shake, sold in a 2.5 oz. bottle, marked with the following:
