• Seafood toxins – Saxitoxin and its derivatives • Green Potatoes – Solanine • Staphylococcal & Streptococcal – Enterotoxin • Clostridium Botulinum - Botulinum
• FSS 3.2.2 Clause 7 Food Processing • How long is too long for foods that are yet to undergo a pathogen control step? • (2) A food business must, when processing potentially hazardous food that is not undergoing a pathogen control step, ensure that the time the food remains at temperatures that permit the growth of infectious or toxigenic micro-organisms in the food is minimised.
Health & Environmental Solutions Network Seafood Toxins • collectively referred to as paralytic shellfish toxins (PSTs), • paralytic shellfish poisoning (PSP), • amnesic shellfish poisoning (ASP), • diarrheic shellfish poisoning (DSP), • ciguatera shellfish poisoning (CFP), • azaspiracid shellfish poisoning (AZP) • Responsible for 750 to 7500 death annually, from up to 0.5 M cased reported • Saxitoxin is one of the most potent neurotoxins • Ciguatoxin CTXs are tasteless, colourless, odourless, heat and acid stable, and stable for at least six months at commercial freezing temperatures. • PCBs, DDT, dioxin and mercury, are also bioaccumulative and persistent

• 7 distinct forms, types A–G. Four of these (types A, B, E and rarely F) cause human botulism. • Only destroyed above 85 deg C for at least 5 minutes. • One of the most lethal substances known. • Block nerve functions and can lead to respiratory and muscular paralysis. • Foodborne botulism, infant botulism, wound botulism, and inhalation botulism or other types of intoxication. • Foodborne - caused by consumption of improperly processed food. • Homemade canned, preserved or fermented foodstuffs.
