Egg Prices Likely to Rise Amid Safety and Cage-Free Debates

In recent years, egg washing and sorting has become one of the core operations in Taiwan's food safety management for eggs. According to regulations by the Council of Agriculture, eggs must undergo cleaning, disinfection, and visual inspection before being marketed to ensure that the shells are free of obvious damage, dirt, or pathogen residues. The washing and sorting process not only reduces the risk of bacterial contamination but also allows consumers to directly identify qualified products at the time of purchase. Since 2017, Taiwan has gradually promoted a nationwide washing and sorting system, using the "washed and sorted" label as a quality guarantee. A supply chain and inspection system based on washing and sorting has thus formed in the market, playing a significant role in enhancing the overall safety of eggs.

However, questions remain as to whether relying solely on terminal washing and sorting as the basis for safety judgment is sufficient to protect consumer health. Animal welfare groups point out that the rearing environment of laying hens directly affects the integrity of the eggshells and their internal nutritional value. Although traditional battery cage systems have advantages in terms of production volume and cost, the limited space and restricted movement often lead to increased stress and decreased immune function in hens, thereby increasing the probability of eggshell breakage and bacterial invasion. In contrast, cage-free systems (such as free-range or barn-raised) provide broader activity space and natural light, resulting in generally better health conditions for hens and producing eggs that are more favored by some consumers for their appearance and nutrition. The European Union has long listed cage-free systems as the minimum standard and conveys animal welfare information to the market through labeling. Some importers and high-end brands in Taiwan have also begun to adopt similar labeling, indicating that consumer attention to farming methods is gradually extending to purchasing decisions.

On the industry side, a complete shift toward cage-free farming faces dual challenges of cost and supply. Cage-free systems require larger land areas and more complex feed management, naturally increasing the unit cost of egg production. According to agricultural statistics, the feed conversion rate and disease prevention and control costs for cage-free systems are higher than those for battery cages. If all operators reform simultaneously, it could lead to a short-term rise in egg prices and even potential supply shortages. Industry representatives stated that without government subsidies or tax incentives, many small and medium-sized chicken farms would find it difficult to bear one-time, large-scale investments. Consequently, the industrial structure could be reshaped, and some small-scale farmers might be forced to exit the market. To address this, the industry calls for the simultaneous design of cost subsidies, technical assistance, and market incentive mechanisms while promoting animal welfare, in order to lower the threshold for transformation.

Consumer demand has also shown diversification. In addition to basic requirements for food safety, a growing number of purchasers list "animal welfare" as one of their selection criteria. Surveys indicate that young urban demographics have a higher acceptance of cage-free eggs and are willing to pay a premium for them, whereas price-sensitive low-income households still prioritize price. This demand stratification has led to the simultaneous emergence of high-priced cage-free brands and traditional cage-produced products that win on price, creating a polarized supply and demand landscape. If the needs of all parties are not properly balanced, a situation may arise where "high-priced good eggs" are restricted to a minority, while the general public remains compelled to accept lower-welfare products, further exacerbating social controversy over food safety and animal welfare policies.

In summary, egg safety should not be an either-or choice between "washing and sorting" and "animal welfare"; rather, it requires finding an optimal balance among food safety inspection, farming environments, industry costs, and consumer preferences. When formulating relevant policies, the government should not only insist on the strict implementation of the washing and sorting system but also simultaneously promote the gradual introduction of cage-free systems. Through subsidies, tax exemptions, and technical support, the government can reduce the transition costs for operators while strengthening the labeling and promotion of cage-free products to enhance consumer recognition and trust. Only through multi-party coordination and institutional improvement can food safety be guaranteed while improving the welfare of laying hens and maintaining the sustainable development of the industry.
