Common Contaminants & Their Impacts:
* Mercury: Found in fish that are higher up the food chain like tuna, swordfish, and shark.
* Effects: Can damage the nervous system, particularly in developing fetuses and young children. Symptoms can include impaired cognitive function, developmental delays, and neurological problems.
* PCBs (Polychlorinated Biphenyls): Industrial chemicals that can build up in fish.
* Effects: Can impair the immune system, disrupt hormone function, and cause developmental problems.
* Dioxins: Byproducts of industrial processes that can contaminate fish.
* Effects: Can disrupt the endocrine system, increase the risk of cancer, and cause reproductive problems.
* Pesticides: Chemicals used in agriculture that can end up in waterways and contaminate fish.
* Effects: Can cause a variety of health problems depending on the specific pesticide, including neurological damage, cancer, and reproductive problems.
* Parasites: Some fish can harbor parasites that can cause illness in humans.
* Effects: Symptoms vary depending on the parasite, but can include nausea, vomiting, diarrhea, abdominal pain, and fever.
Symptoms of Fish Contamination:
* Short-term: Nausea, vomiting, diarrhea, stomach cramps, headaches, dizziness, fatigue
* Long-term: Neurological problems, developmental delays, cancer, reproductive problems, immune system dysfunction
Protecting Yourself:
* Choose low-mercury fish: Fish like salmon, sardines, and shrimp generally have lower mercury levels.
* Eat fish in moderation: Limit your intake of fish, especially those high in mercury.
* Consult advisories: Check local fish advisories for information about mercury and other contaminants in fish from your area.
* Cook fish thoroughly: Cooking fish to an internal temperature of 145°F (63°C) can help kill parasites.
Important Note: The effects of contaminated fish can vary depending on the type of contaminant, the level of contamination, and the individual's health. If you are concerned about the health risks associated with eating fish, talk to your doctor.

Cold chain is an integrated support system that reduce waste in fresh produce. According to studies 50% of fresh vegetables/fruits, 30% fish and 20%meat are lost from production to consumption. This is truer in African countries with challenges in cold chain system. The term implies the use of low temperature control to reduce rotting and extend shelf life of products through the harvest, storage, transportation and marketing. Essentially logistic based the value chain suppo
