Costco Quality Issues: 10 Products Customers Say Have Declined (2026)

The decline in quality of certain Costco items has sparked a wave of discontent among its loyal customers, prompting a deeper look into what's causing this shift. From produce to poultry, and even beloved snacks, the quality dip is a multi-faceted issue with various underlying causes.

The Produce Problem

One of the most notable declines in quality is seen in Costco's produce section. Customers have reported that fruits and vegetables, from broccoli to strawberries, are going bad soon after purchase. An insider's take on this issue reveals an overordering problem at Costco's corporate level, leading to produce sitting in the back until shelf space is available. This results in customers receiving produce that's close to spoilage, a far cry from the fresh, high-quality produce they've come to expect.

Chicken Conundrum

Costco's chicken products, including Kirkland chicken chunks, have also taken a turn for the worse. Customers are finding chewy and tough pieces in their bags, with some questioning the value of their Costco membership due to this decline. The issue extends beyond Costco, as it's a symptom of the wider factory farming industry's problem of breeding birds to grow quickly, leading to muscle degradation and an unpleasant, coarse texture.

Bacon Blues

Costco's bacon, once a favorite, has also seen a decline in quality. Customers describe a gamey flavor and an overly fatty texture, with some comparing the strips to Halloween decor cobwebs. The issue may stem from cost-cutting measures post-COVID-19, impacting the overall quality.

Potsticker Predicament

Ling Ling's Potstickers, a popular Costco item, have also been called out for a potential recipe change. Customers note a decline in flavor and texture, with some speculating that the wrapper is now too thick. However, Costco carries other potsticker brands, like Bibigo, which customers swear by for their superior taste and quality.

Mac & Cheese Disappointment

Beecher's Mac & Cheese, known for its 'World's Best' label, has left some Costco customers disappointed. The sauce lacks flavor, and some speculate that Beecher's is using cheaper ingredients. The cost, too, is a point of contention, with customers feeling it's too high for the current quality.

Oat Milk Woes

Costco's Kirkland Signature oat milk, once a hit, has seen a decline in quality. Customers complain about a lack of froth, a separation issue, and an artificial flavor. This decline in quality highlights the challenge of wider accessibility not always equating to maintaining high standards.

Bacon Crumbles Conundrum

Costco's bacon crumbles, a popular addition to many dishes, have also seen a change in flavor, described as unappetizing and metal-like. Some customers find them too fatty and chewy, and have turned to other brands for a better experience.

Breakfast Sandwich Shrinkage

Costco's breakfast sandwiches, once a convenient and tasty option, have shrunk in size, with thinner bacon slices and a smaller egg. The price, however, remains the same, leaving customers feeling disappointed and questioning the value.

Butter Blunder

Kirkland butter, a baking staple for many, has undergone a recipe change, causing baking disasters. Home bakers report that the butter doesn't soften at room temperature, impacting their recipes. The change in water ratio is speculated to be the culprit, with many recommending switching to more reliable brands like Kerrygold.

Tortilla Chip Tragedy

Costco's tortilla chips, once a crunchy and salty favorite, have lost their appeal. Customers describe them as overly brittle and lacking flavor, prompting some to turn to other brands or even make their own.

This decline in quality across various Costco items raises questions about the brand's commitment to maintaining high standards. While some items may still be favorites for certain customers, the general consensus is that these items are no longer living up to their former glory. As an editorial take, it's important to consider the impact of corporate decisions on the overall customer experience and the brand's reputation.
