“…It was found that cortisol ( p < .0001), dopamine ( p <.02), and noradrenaline ( p < .01) levels were significantly higher in the religiously slaughtered animal group, which led the authors to conclude that meat quality was affected by religious slaughter practices. Moreover, in another study where the capacity of behavioral tests to predict the incidence of DC was tested, a moderate correlation ( r = 0.34; p < .05) between on‐farm cortisol levels and crush test scores (indicating behavior of the animal) was observed, while an excellent correlation between the behavior test and pHu ( r = 0.81‐0.87; p < .01) was observed, indicating merit in combining physiological measurements with behavior observations (De Freslon et al., 2014). Interestingly, high (∼15)‐fold changes in cortisol levels have been observed between baseline and response levels in saliva (Dzviti et al., 2019; Negrão et al., 2004).…”

Meat quality can be affected by stress, exhaustion, feed composition, and other physical and environmental conditions. These stressors can alter the pH in postmortem muscle, leading to high pH and low‐quality dark cutting (DC) beef, resulting in considerable economic loss. Moreover, the dark cutting prediction may equally provide a measure for animal welfare since it is directly related to animal stress. There are two needs to advance on‐site detection of dark cutters: (1) a clear indication that biomarker (signature compounds) levels in cattle correlate with stress and DC outcome; and (2) measuring these biomarkers rapidly and accurately on‐farm or the abattoir, depending on the objectives. This critical review assesses which small molecules and proteins have been identified as potential biomarkers of stress and dark cutting in cattle. We discuss the potential of promising small molecule biomarkers, including catecholamine/cortisol metabolites, lactate, succinate, inosine, glucose, and β‐hydroxybutyrate, and we identify a clear research gap for proteomic biomarker discovery in live cattle. We also explore the potential of chemical‐sensing and biosensing technologies, including direct electrochemical detection improved through nanotechnology (e.g., carbon and gold nanostructures), surface‐enhanced Raman spectroscopy in combination with chemometrics, and commercial hand‐held devices for small molecule detection. No current strategy exists to rapidly detect predictive meat quality biomarkers due to the need to further validate biomarkers and the fact that different biosensor types are needed to optimally detect different molecules. Nonetheless, several biomarker/biosensor combinations reported herein show excellent potential to enable the measurement of DC potential in live cattle.
