COMAR Regulatory Framework: Your Guide to Compliance

In Maryland, the health and safety of individuals with developmental disabilities are paramount, and this is reflected in the Code of Maryland Regulations (COMAR). As direct care professionals, understanding and adhering to these regulations is not just a requirement—it’s a demonstration of your unwavering commitment to excellence in care. While COMAR 10.22 outlines general administrative requirements and health and safety needs for DDA licensees, COMAR 10.15.03 specifically addresses Food Service Facilities, providing detailed guidelines that are crucial for preventing foodborne illnesses.

COMAR 10.22.02.10: Policies and Procedures for Health and Safety

A. A licensee shall develop and adopt written policies and procedures for ensuring: (1) That each individual’s health and safety needs, as identified in the individual plan (IP), are being met; … (16) That State and federally required safety precautions, infection control, and standard precautions are implemented;

This section of COMAR 10.22 emphasizes the licensee’s responsibility to establish clear policies and procedures that guarantee the health and safety needs of each individual are met. This directly includes food safety. Your agency’s policies, guided by this regulation, will detail how food is to be handled, prepared, and served to prevent illness. It also mandates the implementation of “infection control, and standard precautions,” which are directly applicable to preventing the spread of foodborne pathogens.

COMAR 10.15.03: Food Service Facilities – A Deeper Dive into Food Safety

COMAR 10.15.03 provides comprehensive regulations for all food service facilities in Maryland, and many of its provisions are directly relevant to DDA settings where food is prepared and served. This subtitle covers a wide array of topics essential for preventing foodborne illness, including:

• Sec. 10.15.03.04. Food Supplies and Sources: General: Ensuring that all food comes from approved, safe sources.
• Sec. 10.15.03.06. Food Protection During Storage, Service, and Transport: Critical guidelines for maintaining food at safe temperatures and protecting it from contamination at every stage.
• Sec. 10.15.03.09. Food Preparation — Temperature and Cross-Contamination Control: Detailed instructions on preventing the transfer of harmful bacteria from one food item to another, especially between raw and cooked foods.

Core Content Modules: The Four Pillars of Food Safety

Preventing foodborne illness can be simplified into four core principles: Clean, Separate, Cook, and Chill. Mastering these “Four Pillars” will equip you with the practical knowledge to handle food safely in any DDA setting.

Module 1: Clean – Wash Hands and Surfaces Often

Cleanliness is the first line of defense against foodborne pathogens. Many foodborne illnesses are caused by germs spreading from hands to food, or from contaminated surfaces to food. Regular and thorough cleaning is essential.

Key Practices:

• Handwashing: This is perhaps the single most important step. Wash your hands with soap and warm water for at least 20 seconds before and after handling food, especially raw meat, poultry, seafood, or eggs. Also wash hands after using the restroom, changing diapers, touching pets, or coughing/sneezing.
• Sanitize Surfaces: Wash cutting boards, dishes, utensils, and countertops with hot, soapy water after each use. Then, sanitize them with a diluted bleach solution (1 tablespoon of unscented liquid bleach per gallon of water) or a commercial kitchen sanitizer. Rinse thoroughly.
• Clean Produce: Rinse fresh fruits and vegetables under running tap water, even if you plan to peel them. For firm produce, gently scrub with a clean vegetable brush.
• Avoid Cross-Contamination from Cleaning Cloths: Use separate cloths for cleaning different areas (e.g., one for food prep surfaces, another for floors). Wash and sanitize cleaning cloths frequently.

Module 2: Separate – Don’t Cross-Contaminate

Cross-contamination occurs when harmful bacteria from raw foods spread to ready-to-eat foods. This can happen directly (e.g., raw meat juices dripping onto salad) or indirectly (e.g., using the same cutting board for raw chicken and then for vegetables without washing).

Key Practices:

• Separate Shopping: Keep raw meat, poultry, seafood, and eggs separate from other foods in your shopping cart and grocery bags.
• Separate Storage: In the refrigerator, store raw meat, poultry, and seafood on the bottom shelf, below all other foods, to prevent their juices from dripping onto ready-to-eat items.
• Separate Prep: Use separate cutting boards, plates, and utensils for raw meat, poultry, and seafood, and for ready-to-eat foods like salads or cooked items. If you only have one cutting board, wash and sanitize it thoroughly between uses.
• Never Reuse Marinades: Do not reuse marinades from raw meat or poultry unless you boil them first to destroy harmful bacteria.

Module 3: Cook – Cook to the Right Temperature

Cooking foods to the correct internal temperature is the only way to ensure that harmful bacteria are destroyed. Color and texture are not reliable indicators of doneness.

Key Practices:

• Use a Food Thermometer: This is your most important tool for ensuring food safety. Insert the thermometer into the thickest part of the food, avoiding bone.
• Safe Minimum Internal Temperatures:
  • Poultry (whole, ground, and pieces): 165°F (74°C)
  • Ground Meats (beef, pork, veal, lamb): 160°F (71°C)
  • Beef, Pork, Veal, Lamb (steaks, roasts, chops): 145°F (63°C) with a 3-minute rest time
  • Fish and Seafood: 145°F (63°C)
  • Eggs: Cook until yolk and white are firm. Dishes containing eggs: 160°F (71°C)
  • Leftovers and Casseroles: 165°F (74°C)
• Keep Food Hot: After cooking, keep food hot (135°F/57°C or above) until serving if it’s not going to be consumed immediately.

Module 4: Chill – Refrigerate Promptly

Bacteria multiply rapidly between 40°F (4°C) and 135°F (57°C)—this is known as the “Danger Zone.” Prompt refrigeration is crucial to slow or stop bacterial growth.

Key Practices:

• Refrigerate Perishables Within 2 Hours: Refrigerate or freeze perishable foods, prepared foods, and leftovers within 2 hours. If the ambient temperature is above 90°F (32°C), refrigerate within 1 hour.
• Divide Large Portions: Divide large amounts of hot food into shallow containers before refrigerating to help them cool more quickly and evenly.
• Thaw Safely: Thaw frozen foods in the refrigerator, in cold water (changing water every 30 minutes), or in the microwave. Never thaw foods at room temperature.
• Check Refrigerator Temperature: Ensure your refrigerator is set at or below 40°F (4°C) and your freezer at 0°F (-18°C). Use an appliance thermometer to verify.

Practical Application: Real-World Scenarios for DSPs

Let’s apply these principles to situations you might encounter in your daily work. Your ability to think critically and act decisively in these moments is invaluable.

Scenario 1: The Unrefrigerated Potluck Dish

You arrive at a community gathering for individuals you support, and a family member has brought a large pasta salad with mayonnaise that has been sitting out on a table for 3 hours in a warm room. It smells fine, but you know it contains perishable ingredients. What is your concern, and what should you do?

Considerations: Mayonnaise-based salads are potentially hazardous foods. The “Danger Zone” for bacterial growth is between 40°F (4°C) and 135°F (57°C). After 2 hours at room temperature (or 1 hour if above 90°F), perishable foods can become unsafe due to rapid bacterial multiplication, even if they smell and look fine. The longer it sits, the higher the risk of foodborne illness.

Action: Politely and discreetly approach the family member or event organizer. Explain your concern about the time the pasta salad has been unrefrigerated and the potential for bacterial growth, even if it appears fine. Suggest that for the safety of everyone, especially the vulnerable individuals you support, it would be best to discard the dish. Offer to help arrange for a safe alternative if needed. Emphasize that this is a standard food safety protocol to protect everyone’s health.

Scenario 2: Cross-Contamination Concern

You are preparing dinner for an individual, and you just finished cutting raw chicken on a cutting board. You then plan to chop fresh vegetables for a salad using the same cutting board without washing it. What is the risk, and what should you do?

Considerations: Raw chicken often carries harmful bacteria like Salmonella or Campylobacter. Using the same unwashed cutting board for ready-to-eat vegetables creates a high risk of cross-contamination, transferring these bacteria directly to food that will not be cooked. This can lead to serious foodborne illness.

Action: Immediately stop. Explain the importance of preventing cross-contamination. Thoroughly wash and sanitize the cutting board, knife, and any other utensils that came into contact with the raw chicken using hot, soapy water, followed by a sanitizing solution. Alternatively, use a separate, clean cutting board and utensils for the vegetables. Always wash your hands thoroughly with soap and water after handling raw meat, poultry, or seafood.

Scenario 3: Improper Thawing

An individual you support wants to have chicken for dinner, and you realize the chicken is still frozen solid. To speed up the thawing process, you decide to leave it on the kitchen counter for a few hours. What is the food safety risk, and what should you do instead?

Considerations: Thawing frozen foods at room temperature allows the outer layers of the food to warm up into the “Danger Zone” (40°F – 135°F or 4°C – 57°C) while the inside remains frozen. This creates an ideal environment for bacteria to multiply rapidly on the surface, even before the food is fully thawed. Cooking may not destroy all toxins produced by these bacteria.

Action: Never thaw perishable foods on the counter. The safest ways to thaw chicken are: in the refrigerator (plan ahead, as this can take 24 hours per 5 pounds), in cold water (changing water every 30 minutes), or in the microwave (cook immediately after thawing). If using the cold water or microwave method, ensure the chicken is cooked without delay once thawed.
