Food Safety Tips for Lunar New Year: A Guide for Hong Kong's Food Lovers

As the Lunar New Year approaches, Hong Kong citizens welcome the festive feasts and traditional delicacies. From the communal sharing of Poon Choi (盆菜) to the sweet indulgence of glutinous rice cakes, food plays a central role in our celebrations. While we prepare for gatherings with family and friends, it's crucial to prioritize food safety, an aspect often overlooked in the excitement of the holiday season. From shopping for food safety to avoiding choking hazards and how to store leftovers best, let's explore essential safety tips for enjoying traditional Chinese New Year food while keeping our loved ones healthy and safe.

-

Smart Shopping for Traditional Chinese New Year Snacks

The iconic candy box, also called Chuen Hup (全盒), is a staple in most homes during the Lunar New Year celebrations in Hong Kong. While these containers filled with pistachios, melon seeds, and candies bring joy to visitors, choosing safe options requires attention to detail.

-

Avoiding Food Colouring in Candies

When selecting candies for your Chinese New Year candy box, be particularly mindful of artificial food dyes. Research shows that synthetic colorants like Red 40, Yellow 5, and Blue 1, which create unnaturally vibrant hues in candies, are linked to behavioral changes and hyperactivity in children . Instead, look for treats with more subdued colors from natural sources like butterfly pea flowers, beetroot, or turmeric.

What to Look for in Safe Traditional Snacks

For traditional Chinese New Year snacks, quality indicators are crucial. Natural pistachios should have a light beige to the pale cream-colored shell with occasional dark spots. Avoid those with uniformly bright white or chalk-like shells, as this often indicates bleaching with hydrogen peroxide, which can leave harmful chemical residues. Similarly, when selecting melon seeds, look for ones with a natural matte finish rather than a glass-like shine. An unnaturally uniform, high-gloss appearance often suggests excessive waxing with potentially harmful substances that can accumulate in the body over time.

Preventing Choking Incidents During Festivities

Traditional Lunar New Year food, particularly glutinous items like tong yuen (湯圓) and rice cakes, presents significant choking hazards, especially for young children and elderly individuals with compromised swallowing abilities. When preparing these foods, try to modify them to reduce choking incidents. For tong yuen, cut these glutinous rice balls into quarters before serving, and ensure they're thoroughly cooked until soft but not overly sticky. When serving nin gou (年糕), slice it into thin strips or cubes no larger than 1 inch wide, and consider steaming until extra tender rather than the traditional pan-frying method, which can create a chewier texture.

Creating a safe eating environment when eating these foods minimises the chances of choking. Avoid serving these foods during animated conversations or festive games, and maintain proper lighting so everyone can see their food. For elderly relatives with dentures, swallowing difficulties, or young children, always have at least one person at the table watching for signs of distress.

Serving and Preparing Poon Choi (盆菜)

-

Safe Preparation of Poon Choi
Poon Choi, a quintessential Lunar New Year dish in Hong Kong, requires meticulous handling due to its complex preparation process and multiple ingredients. The preparation of poon choi involves various ingredients requiring different cooking methods, from braised meats to seafood and vegetables. Each component undergoes distinct preparation processes, including marinating, pre-cooking, cooling, and final assembly. This complexity creates multiple critical points where food safety can be compromised if proper procedures aren't followed. To maintain food safety during preparation, implement a systematic approach to temperature control. Studies show that leaving food at room temperature for extended periods allows foodborne pathogens to multiply rapidly, potentially producing heat-resistant toxins that persist even after reheating . When preparing ingredients in advance, cool them rapidly using an ice bath system, divide larger portions into smaller batches and place them in shallow containers to accelerate the cooling process. Store all pre-cooked components at 4°C in sealed containers to prevent cross-contamination.

-

Safely Serving Poon Choi

When serving poon choi, temperature management is crucial. Reheat the dish thoroughly until the core temperature reaches at least 75°C, verifying with a food thermometer if possible. For extended serving periods, maintain the temperature above 60°C using appropriate heating equipment, like a gas stove. When sharing food with others, use designated serving chopsticks to prevent cross-contamination between diners. This practice becomes especially important during large gatherings where multiple people share the same dish over an extended period.

How to Safely Save Leftovers After Chinese New Year

Lunar New Year celebrations typically involve abundant food preparation, often leading to significant leftovers at the end of the holiday. Inappropriate storage of food leftovers could cause foodborne illnesses, making food storage imperative.
-
Critical Temperature Control and Storage Guidelines
Time and temperature control are crucial in preventing bacterial multiplication. Potentially harmful bacteria can multiply rapidly between 4°C and 60°C in foods, making refrigeration crucial when storing leftovers. You should refrigerate all leftover dishes within two hours of cooking or serving. Any food left at room temperature for more than four hours should be discarded, as this duration allows dangerous levels of bacterial growth and potential toxin production.

-

Glutinous rice cakes and puddings are susceptible to moisture-induced mold growth, even under refrigeration. These items require careful monitoring, and any signs of mold growth or unusual taste indicate potential contamination, requiring immediate disposal. People often slice off the portion with mold while thinking it's safe to eat the section without the mold. However, once mold has developed, even a small part of it has already spread to the underlayers of the food product. Disposing of the whole portion at this stage is advised.

-

If you decide to store leftovers, implement a strict three-day disposal policy for refrigerated ones, regardless of how fresh they look. You should store leftovers in sanitized, airtight containers to minimize cross-contamination and maintain proper food quality.
-
Sniff Test - Is it Safe?

The common practice of "sniff testing" tells us that it's safe to eat if it doesn’t smell abnormal. However, this test provides a false sense of security, as harmful bacteria can thrive without producing detectable odors or visible changes. Even apparently fresh-looking food can harbor dangerous levels of pathogens. When reheating leftovers, ensure the core temperature reaches 75°C and only reheat once. Multiple reheating cycles can create conditions favorable for bacterial resistance.
