Study Notes
Food Safety Risk Assessment - Unit 7
- Roundup weedkiller "probably" causes cancer, according to a WHO study. The active ingredient, glyphosate, may also be carcinogenic for non-Hodgkin's lymphoma.
- Roundup is the world's most widely used weedkiller. WHO's cancer agency (IARC) classified glyphosate as "probably carcinogenic to humans".
- Monsanto, an agricultural company, produces Roundup.
- A European agency says glyphosate is unlikely to cause cancer in humans.
- 54,000 active Roundup lawsuits remain.
- Many lawsuits have settled out of court, with Monsanto paying approximately $11 billion.
- To classify as Class 1 carcinogen, epidemiological and experimental animal studies need mechanistic data describing the causal association.
Microbiological Risk Assessment
- Steps in microbiological risk assessment include: hazard identification, exposure characterization, risk characterization, and hazard assessment.
- Microorganisms like bacteria, viruses, parasites, and fungi can cause disease in humans.
- A pathogen is an organism (e.g., bacteria, viruses, parasites, and fungi) causing disease.
Case Study: Salmonella in Eggs
- FDA upgraded a recall of eggs for salmonella to "serious" health risks or "death".
- A contamination of salmonella in some 3 million eggs led to a recall by French authorities.
- An outbreak of Salmonella Enteritidis infections linked to Polish eggs affected multiple European Union (EU) and European Economic Area (EEA) countries, resulting in at least 1,412 reported cases.
One Health
- One Health is an integrated approach to sustainably balance and optimize the health of people, animals, and ecosystems. It emphasizes the interconnectedness of human, animal, and environmental health.
Additional Notes
- Linear extrapolation is the common method of extrapolating data at low concentrations for dose-response relationships in tumor formation studies.
- The maximum daily dietary exposure to chemicals is estimated at 30 ng/person. Based on this estimate, the chemical may need to be assessed based on a priority approach for evaluation.
- Information on the origin of the word "Salmonella" was included. The name stems from D. Salmon.
