It is true that food labeling and supply-chain transparency are real concerns in the global food industry. Most countries require traceability systems so products can be tracked back to their source, and violations—when they occur—are typically handled through recalls, fines, or enforcement actions rather than broad, undisclosed practices going unnoticed.

The complaints mentioned (such as texture, smell, or quality differences) are also common consumer experiences that can arise from normal factors like storage conditions, batch variation, or processing methods, not necessarily fraud or substitution.

Without confirmed evidence from regulators, inspections, or documented recalls, the allegations in the passage should be treated as unverified claims rather than established facts.
