Injection, most often refered to as "seasoned" on packaged meats, cannot be the explanation for Robert's mysterious experience. Only steaks from low grade or ungraded beef are seasoned. We may never know as Robert did not reveal any details about the meat and has been absent since his original post here.
The solution injected is a brine, not water, and is usually limited to approximately 17% by weight. By law the amount must be disclosed on a product's label.
Community has recently discussed another potentially para-normal SV experience and Robert's may be one more. Since the prior occurrence and to help prevent these unexplained events i have made an aluminum foil pyramid and placed it on top of my Anova during cooks. It has been totally successful in preventing occurances similar to Roberts.
