A comprehensive investigation by the Consumer Council reveals concerning findings about pantry staples, while 18 brands earn top safety ratings
Hong Kong households may want to take a closer look at their pasta supplies. The Consumer Council’s latest test on 35 pre-packaged dry pasta products has uncovered that every single sample contained light foreign matter—including insect fragments—with some brands also testing positive for pesticide residues and a toxin commonly known as “vomitoxin.”
Conducted between April and May 2020, the study examined 35 pasta samples ranging from fusilli and macaroni to spaghetti and linguine, priced between HK$4.9 and HK$57.9 per pack. Among these, three products were specifically marketed for infants and toddlers under 36 months old. The results have sparked widespread discussion about food safety standards in everyday staples.
What the Tests Revealed
Insect Fragments Found Across All Samples
Every pasta sample tested contained light foreign matter, including insect fragments, hair, stone particles, metal shavings, natural fibers, or plastic pieces. The quantity per 225-gram sample ranged dramatically—from as few as 4 fragments to as many as 548.
Nissin Foods and Marks & Spencer recorded the highest levels, with 548 and 271 insect fragments per 225 grams respectively. The Consumer Council noted that these figures point to significant room for improvement in hygiene standards.
However, authorities emphasize that no studies have conclusively demonstrated these foreign particles pose health risks to humans. Since pasta undergoes high-temperature cooking before consumption, most bacteria are eliminated during the process.
Pesticide Residues and Toxin Concerns
The investigation detected pesticide residues in 23 samples, with 12 containing multiple types. Alarmingly, two products labeled as “organic”—Castagno and Delverde—still showed trace amounts of pesticides.
For infant-specific products, Bellamy’s Organic was the only brand free of pesticides. Wakodo and Hakubaku contained glyphosate levels of 0.192 mg/kg and 0.036 mg/kg respectively. These concentrations remain below legal limits under Hong Kong’s Pesticide Residues in Food Regulation, and proper serving sizes (12 to 30 grams per meal as recommended) pose minimal health risks.
Additionally, 23 pasta samples tested positive for deoxynivalenol (DON), commonly called “vomitoxin,” with levels ranging from 36 to 506 micrograms per kilogram. All fell well below the European Union’s maximum limit of 750 micrograms per kilogram for dry pasta.
18 Top-Rated Pasta Brands for Safety
Despite the concerning findings, the Consumer Council awarded five-star safety ratings to 18 pasta products. These brands demonstrated the lowest levels of contaminants and foreign matter. Full details of the complete test results and brand list are available on the Consumer Council’s official website.
Industry Responses
Manufacturers offered varied explanations for the findings. Barilla suggested that detected fragments might be false positives from wheat bran residue. Nissin stated its products intentionally include visible wheat bran for added fiber and minerals, which laboratories may misinterpret as insect particles.
Castagno commissioned independent retesting that showed no insect, plastic, or stone fragments. De Cecco acknowledged robust pest monitoring systems but noted insects can enter through packaging micro-pores or due to improper retail and home storage.
Regarding pesticides and DON, brands including Tesco, Jamie Oliver, Sainsbury’s, and M&S confirmed compliance with EU and Hong Kong food safety regulations. San Remo provided documentation showing pesticide residues far below maximum limits.
5 Essential Tips for Buying and Storing Pasta Safely
To ensure your pasta remains safe from purchase to plate, follow these expert recommendations:
-
Inspect packaging integrity – Check for tears, cracks, or poor seals. Look through clear packaging for visible mold, foreign objects, or insects. Avoid packages with moisture or unusual powder inside.
-
Store in optimal conditions – Keep pasta in a cool, dry, dark place away from direct sunlight. After opening, transfer to airtight containers such as glass jars or vacuum-sealed boxes to block moisture and pests.
-
Examine before cooking – Look for discoloration, mold, or tiny holes in the pasta. If any signs of spoilage or infestation appear, discard the product immediately rather than risking consumption.
-
Read allergen labels carefully – Check for wheat and gluten content. Those with celiac disease or gluten sensitivity should choose products clearly labeled “Gluten-Free,” often made from brown rice or corn flour.
-
Practice first-in, first-out rotation – Pay attention to best-before dates and consume opened pasta promptly. Avoid bulk buying during sales unless you can use the products within a reasonable timeframe.
Looking Ahead
This investigation serves as a reminder that even pantry staples require vigilance. While the Consumer Council confirms that proper cooking eliminates most bacterial risks, consumers are encouraged to remain informed about product quality.
