The “Date of Guarantee” was changed easily. A medium-sized food company tampered with the date of production of the packaging, and used a cotton swab to “diluent” to lightly apply a variety of “big” food packaging with different font production dates, product batch numbers, etc., for a few seconds. Witness the miracle. Whether it is plastic bags, aluminum cans or paper boxes, the production date is basically smeared!
No matter if it is a code or a code, it can be altered as long as it uses ink. A coding equipment supplier said that the printing time information can be arbitrarily adjusted within 3 years! Consumers are kept in the dark by "hidden rules." Local food supervision departments often remind consumers that they can check whether the production date is "ambiguous" and whether the printing date has "ink and darkness" around the printing date. Rights protection. Some industry insiders frankly stated that these identification techniques have now basically failed with the “upgrading” of altering methods.
Regarding the problem of altering the shelf life of foods, many people know from large companies to small vendors. A well-known packaging machinery manufacturer in Beijing revealed that, at present, more effective countermeasures, the use of laser printers to the production date and other information with the laser "burned" on the packaging. But for the "laser machine" food industry many manufacturers stay away. The main reason is that the price of gold is high, and the price is about 2 times that of using ink equipment.
Some large companies in the food industry adopt an “internal control risk” attitude toward the date of alteration: special codes are added to the code information such as the production date, and one code corresponds to only one batch of products. In this way, when the product date is altered and there is a quality dispute, the company will give evidence to seek exemption. However, after the company seeks to “go it alone,” consumers are still blindfolded and become the biggest victims. Prevention of Food “Never Overdue Period” Should Address Both the Problem and the Present The current issue of “distortion” of food shelf life is becoming one of the most prominent hidden dangers of food safety. Relevant experts called for the urgent need of regulatory authorities to take measures to combine “technical defense” and “human defense” and all efforts should be made to stop it.Only the supervision of the whole society, various 'losing strokes' would have no place to hide.
